I've not been writing a lot here, lately, because so much of it would be about depression*, and I'm rarely proud of what I write about it when I'm in the middle of dealing with it. But definitely go read what Wil Wheaton has to say about it, because holy shit does he nail it, and in a really good, useful, positive way. This recent post is a great place to start.
*and the rest would be about sex — another pretty poor blogging topic. ;)
