We have had several suggestions via Skribit this week. Some are using it to make snarky comments that stay on the home page and not really because they expect a post about it on http://www.techdrawl.com. We'll leave them up for awhile.
I have not applied for YC. I was still finishing up college and was never really in a position to be able to move and have a cofounder that could do the same. And when I did graduate, Georgia Tech invested in us. http://www.gatech.edu/newsroom/release.html?id=2356
I'm not sure we are comfortable giving this info out yet (although we have a live # of blogs on our homepage), but about 65% of all account holders are what we would consider active, and if you wanted to get nitpicky ~10% are very active. This does not include users that do not use us with a blog, but instead just to keep track of suggestions/people they follow.
As I mentioned in my post though, this is with no formal marketing efforts aside from me blabbing about it on my blog. Hopefully in 2-3 months we'll be in a position to market and spread the word out a lot more.
