Almost everyday. However, there are weekend days that I don't visit at all. It's important to have some balance in what you do, and it wouldn't be good for the site if I couldn't go a day or two without visiting. Comments to the effect that you all appreciate hubski for the quality of interactions that you find mean far more to me than any user metric. It's funny that such a statement might be difficult to believe. We have this internet that lets everyone in the world connect, but by-and-large every effort is to concentrate upon the quantity of those connections rather than the quality. Hell, we have the ability to provide input, but even then, the majority of platforms are designed around a one-to-many one-way type of communication. I've said it countless times, but this place is about something that I wanted to exist. I enjoy talking to you all, and the ability to share my thoughts with people that are looking to have a conversation. I actually prefer hubski, but recall that I thought it seemed a bit pretentious when I was making the decision for site text.
I find myself visiting hubski more often every day since the day I registered, unfortunately I get most of the replies while I'm sleeping (except for yours and c_hawkthorne's reply). Discussion seems to go a bit slower for me than the rest of the users.
