StackOverflow announced yesterday that our firm Union Square Ventures led a $6mm round of financing in their company yesterday. My partner Brad is joining Stack's board and he will post about this investment on usv.com sometime this week.
However, given Kid Mercury's persistent advocacy of niche communities here at AVC, I thought I'd make a couple remarks.
Stack makes StackExchange, a hosted software solution for creating niche communities. It is the software that powers the super popular StackOverflow community for programmers and also communities like ServerFault (for sys admins), SuperUser (for tech enthusiasts), MathOverflow (for math geeks), and many more.
These communities are all about helping each other out. You want to know the magnitude of graham's number? Well then head over to MathOverflow and ask the question and get some help. You want to know about LVM Mirroring vs Raid 1? Then head over to ServerFault and ask the question and get some help.
We think this is a powerful new take on the broadly popular Q&A model on the web. You can go to Yahoo! Answers, Mahalo, or Quora and ask any question. But our bet is vertical communities will make better Q&A sites in the long run as people aggregate around what they know and what they need to know.
So if you have a niche community that is vibrant and in need of a Q&A solution, then look for StackExchange 2.0 which is coming soon.
