I am a huge fan of gathering, analyzing and evaluating data. Creating statistics and colorful graphs just has something to it. But the interesting part is not necessarily the data itself, it’s the data about the data. How often does something occur, at which time and by whom are very important characteristics when it comes to creating patterns.
For example, let’s look at the two weekday-graphs of two different WhatsApp chats of mine.
Weekdays Chat A

Weekdays Chat B

It is not that hard to figure out the difference between those two graphs. The number of daily messages in A is pretty stable except for Friday and Monday, which are two extremes. Maybe this could be about a friend group planning what they’re going to do on the weekend? The general quantity of messages is also lower as in figure B. The second chat also has a huge gap between Sunday and Saturday. Could this be a group chat related to work? Or is it someone close who happens to live in the same house?
You can see that it is possible to gather connections and create assumptions about certain topics without even looking at the data itself. Now let’s take a deeper look.
Days-Heatmap Chat A

How interesting. We can see that the group is most active between the end of January till May and spikes again in October. If you happen to live in Austria, you probably know what that means. See, in most areas, the Austrian summer break for students lasts from June till the beginning of September while Christmas lasts from December to January. There is also one small break during November. You can clearly see that this could be a chat between friends who happen to be students but don’t have the same classes together. They probably spend a lot of their free time together, which explains the lack of data during the breaks. No one texts another person while they’re sitting next to them… right?
Days-Heatmap Chat B
-
-
+
We can see that the amount of messages remains pretty stable. This could prove our theory of two people in the same household as true. Maybe the gap in August could be a planned vacation?
It would be pretty frighting if I told you all our assumptions were correct. Right? You may now probably recognize that metadata is a lot more valuable than you originally thought. But what conclusions can we draw from this newly gained awareness?
Most people rely on the encryption of their messaging apps. If no one can read my data then I am safe, right? No. As we can see, an attacker does not need access to your communication in order to gather valuable information.

“Internet”, an unknown 90’s stock image
Back then, websites were more like digital diaries. Each website felt like stepping into the creator’s mind – a place where they poured their heart and soul, sharing their interests, hobbies, and thoughts with the world. Sadly, im simply too young to remember such a place in detail but i was able to experience some of it during my first steps on the internet back in 2009, when most of these sites were still up and big companies did not yet have the upper hand over the internet..
Moreover, the internet provided a platform for enthusiasts to come together and create niche communities. From fan forums to personal blogs, people found like-minded individuals who shared their passions, creating a sense of camaraderie that was truly special.

The Melonland forum
Each blog was an explosion of colors and creativity. Every website had its own distinctive flair, reflecting the personality of its creator. Whether it was the playful use of neon colors or the subtle elegance of pastel shades, each one stood out from the rest, showcasing the artistry and individuality of its designer.
Web pages were adorned with animated backgrounds, cursor trails, and unique icons. Yes, some might argue that it could get overwhelming at times, but it was just this boundless creativity that made every browsing experience a delightfully unpredictable adventure.

Gifypet, a gif pet creation tool (??!!)
In those days, the internet was driven by its users. Their sites were designed to engage and entertain, not to bombard visitors with advertisements or collect data for profit. Online interactions were genuine, and social media platforms were still in their infancy, free from the burden of algorithms and targeted advertising.
The online community was a powerful force, shaping the internet’s evolution through collaborative efforts and shared feedback. User-generated content, such as forums, chat rooms, and guest books, encouraged open discussions and fostered a sense of belonging in the digital realm.

As time passed, the internet underwent a transformation. The rise of social media giants and corporate interests gradually shifted the balance of power from users to profit-driven organizations. The personalized, colorful web pages became streamlined, conforming to modern design standards and sacrificing individuality for uniformity.
Online communities lost some of their authenticity, as algorithms began to dictate content and user engagement. The once user-centric internet was now influenced by commercial interests, and our online experiences were curated based on our data, making it harder to find the hidden gems we once stumbled upon.

Steven K. Roberts and “Behemoth”, taken from Teknomadics
In 1983, Steven K Roberts set out on an extraordinary adventure, pedaling across the United States on a recumbent bicycle he called “Winnebiko” (his later models were called “Winnebiko 2” and “Behemoth”). What made this journey unique was the impressive array of technology packed into the bicycle’s streamlined body, including solar panels, a computer, a ham radio, and other cutting-edge gadgets.
Roberts’ vision was to merge technology and nomadic living, proving that one could work remotely and stay connected with the world while exploring new horizons. As he traversed the American landscape, he chronicled his experiences and technological innovations in articles for “Computer Currents” magazine, capturing the imaginations of readers everywhere.

Steven and his second bike, taken from his website
During the 1980s, Roberts’ audacious endeavor sparked both awe and skepticism. Many people were fascinated by his nomadic lifestyle and the creative use of technology to maintain communication and work on the go. They saw his journey as an inspirational tale of freedom and possibility, challenging the traditional notion of work confined to brick-and-mortar offices.
However, others viewed Roberts’ quest with doubt and disbelief. The idea of working remotely and relying on technology to sustain such a lifestyle was seen as an eccentric and unrealistic notion (lol). Skeptics questioned the feasibility of his technological setup and doubted whether it could lead to any meaningful career.
Nonetheless, the mixture of reactions, whether supportive or doubtful, only fueled Roberts’ determination to prove that the concept of remote work and digital nomadism could be more than just a pipe dream.

Steven K Roberts’ bold journey as the first digital nomad was truly something new. His fusion of technology and nomadic living challenged societal norms and laid the groundwork for the modern-day remote work revolution. Although met with both curiosity and skepticism, Roberts’ determination and vision proved that the impossible can become possible with courage and creativity.
The internet revolution that followed in the 1990s and early 2000s further expanded the possibilities for remote work and nomadic living. Today, countless individuals around the globe are living the dream that Roberts dared to dream decades ago.
