I found an insightful discussion about SO/SE (StackOverflow/StackExchange) business model and going for VC money on 37signals. It looks like everything has been said, and the outcome is just remained to be seen. Some key points well noted there were:
- A developer Q&A site cannot scale, since it’s a niche site.
- The clones of a Q&A site are too easy to build, expect a lot of competition.
- A Q&A platform cannot scale, because it’s just too easy to build. What happened to forums (phpBB and vBulletin), will happen to social Q&A platforms. Expect a race to the bottoms.
- There is already a good competitor: www.qhub.com, wait for more to come.
