Yesterday, the blogging company Six Apart announced that it had acquired the micro-blogging site Pownce. Pownce will cease to exist as a standalone website and cofounder Leah Culver, who was one of the entrepreneurs under 30 profiled in our October issue, will be moving to Six Apart and shutting down her own website. No financial terms were disclosed but considering the current economic climate, the dominance of Pownce's main competitor Twitter, and the fact that Six Apart just laid off a bunch of people, it's unlikely this was a huge exit—if cash changed hands at all.
