I thought of this because I wanted to acknowledge @kfwyre's recent posts... I appreciate the time and effort they've put into organizing community-focused events and groups (Timasomo, the Steam Gifting Group). I also like that they make interesting Ask-style threads, too. Plus, they make a heck of a lot of thoughtful, in-depth comments that are lovely to read.
