Even if our objective is somehow to provoke a reaction, we are still seeking some sense of... connection with others.

Indeed! always seeking for a somewhat sense of connection with others. Although in my case, never really in the quest to find out any sort of echo chamber. But on the contrary, I'm often in the lookout for someone to disagree with my way of thinking and point of view just to see if I learn something new.

It has long interested me how 70-75% of the greater world are extraverts while 25-30% are introverts, but in the online environment the proportions are almost reversed.

Interesting observation. According to our age, I already had the opportunity to confirm these curious experiences from those old amateur CB radio days long before the internet was even a thing within our reach. Every time we organized those eventual meetings in person, it usually was really difficult to associate the character we had in front of us with the one we already thought we knew through the airwaves. Conversely and interestingly, almost everyone already seemed to know me and identify me very quickly just by looking at me briefly from the distance. Hahahaha

No, the book never came to pass because Sherry Turkle at MIT beat us to it with her seminal book Life on the Screen which answered many of the questions we were looking at.

Great, I think I've heard before about Sherry Turkle and much of her work as an expert student of cyberculture and human behavior on the internet. I even think to remember reading some of her other books on the subject. However, this "Life on the Screen" that you mention, I don't think I have read it yet. So, I guess I'll have to look it up to read it. :)

Do we feel any greater sense of belonging? Or do we remain just as alone as we were before?

Oh! I really believe that I've always been a great outgoing and observant hermit that I belong wherever I go because I often fit very quickly into all kinds of environments. I suppose this always comes determined by the pleasant zen company of my own curious nature and rich observant solitude even when I am alone.

Music can also be a point of connection. In ancient times, people would gather around the fires and drum and sing songs of the tribe's history and endeavors. Music remains a point of connection.

Haha yeah, talk me about it! };)

Music can also be a representation of the sound of a person's spirit.

Did you listen to the music?

Chances are that the tune I included is something you've never heard of, in a genre you're not familiar with. It's the sort of thing I listen to much of the time when I'm working.

You betcha I did listen the music you shared! Which by the way, reminds me a lot of a handful of those chillout old tunes that I created myself almost a quarter of a century ago.
But since most of these, they no longer exist online anymore. Then let me share you an older tune in my evolutionary road to create one slightly more similar to the Emro groove.

Yeah, this old melody only with the intention of continuing to lift your spirit with background music while you work. And also, so that you can fatten even more your world's largest collection of music made by unknown people no one have ever heard of before.

So there you go my friend! Now you can boast before your friend Mikey that you still conserve the same delightful vice after so many years without having seen him again.
