I just tend to be long winded :P. When speaking IRL my replies are a lot shorter and I find it difficult to figure out the words I want to say. I spend a lot of time on my longer comments, as I frequently have to pause to find the right word.

I'm only aware of how long my comments tend to be because I frequently hit the comment size limitations of several websites (Facebook, IndieDB, etc). As for commenting on how much the Beatles suck... I can assure you I've had longer comments on topics I'm more interested in. Usually when something grabs my attention I put all of my focus into it, leading to longer comments.

That's part of the reason I found the word/character counts interesting. Is that longer comments tend to be new/original ideas that need explaining, or on topics where there is a lot of material to cover. On Reddit, there doesn't tend to be a lot of that type of conversation going on (it mostly happens in the "true" subreddits, and the other more serious subreddits). On Hubski, the whole site is kind of focused towards that.

As for other stats... I can't think of any off the top of my head. I think the only thing I was interested in and couldn't find was the number of users that 1. have registered an account, and 2. that actively use the website (say in the past month or two). When I joined Hubski I wasn't sure how big of a community it was (I'm still not that sure). If I had to take a guess, I'd wager it's probably somewhere between 200-800 active users. But that feels kind of high compared to the content I see. And I'm not sure if that's just due to hubski's design or if it's due to how many users there are. A TMI stat for that would be nice.

I think another nice feature would be to see the users who submit the most content to the tag currently being viewed. That way if I go to, say, the #gaming tag, I can see who actively submits stuff (so I can follow them). As it stands, I just kind of have to look at the content and make my best guess.
