This may run counter to some of the other comments in this thread, but at the end of the day, it's just the internet. hubski is just a website, and in my opinion you're absolutely overthinking it. Again, it may be that no one agrees with me here; I'm just telling it like I see it.
I love the regular commenters here, but when I joined hubski it was for the articles. I like to read articles on stuff I don't know about. hubski makes this easy and more fun than doing it alone. That's why I'm here. You're here for a different reason, perhaps kleinbl00 is for a third, lil for a fourth. Who cares? hubski's just a place you go, I go, we all go. You might use it partially as a sounding board, insomniasexx might use it to share thoughtful long articles, I might use it to talk music with ButterflyEffect or bfv. Someone else might just post their blog for feedback. None of those things is better or worse than any other.
As far as functionality, you tag every one of your posts something specific, right? So no one who can utilize hubski's basic features has a single reason to complain.
This last bit isn't remotely intended to be an insult -- but remember the axiom that no one is paying as much attention to you as you are. I think it applies here, in a completely positive sense. You don't have to defend yourself for shit.
