It was a bit oddly worded - Apologies. I was specifically responding to when you said -
I mean, most of the people except for your family were just "random people in real life" before they became your friends. Is there really a difference, especially now, when digital life has become increasingly more equivalent to "real" life?
I personally don't do much following of people here - I fear the echo chamber of my own experience - But I definitely know people here, and I have a rapport with many. the interactions I have with those people are the reason why I return here.
Every social aggregator has a "thing". It could be "absolute" anonymity, it could be paid membership to ensure quality content, it could be anything. Community, the "X axis", is the "thing" that Hubski has. If the the X axis isn't what you're into, then I don't think you're going to get a whole lot out of the site. Similar content can be found on pretty much any other aggregators, (or in a Newspaper, the analog aggregator), and their functionality might be more like what you're looking for.
Don't get me wrong, i'm not trying to actively dissuade you from hanging out, I'm just trying to impress upon you the general concept of what hubski "is", and how it sees community building with random people on the internet as its strength.
