I just relaunched this blog to focus exclusively on social gaming. Before this week, however, I was also writing about entrepreneurship in general. Since you're probably looking to avoid advice on how to be more productive, etc., I've compiled a short list of social gaming related posts (and virtual worlds because there are some interesting overlaps).
So the greatest hits so far:
Puzzle Pirates v. Club Penguin
A Review of Kaneva, a virtual world
Ebays stops trading of virtual goods
Wiicade.com - Trespasser in the Walled Garden
Game Geek - I Like it Long and Hard, so Kill Me.
Starbucks Survey: Ever Heard of Second Life?
