Startup Ideas We'd Like to Fund (2008)

#13 Online learning is an interesting one for YC. It looks like they couldn't find anyone doing it well enough, so they started their own startup school - https://www.startupschool.org/

#22 A web-based Excel/database hybrid - Should have invested in Google.

#25 A Craigslist competitor seem obvious, but no one can take the crown from them. Not even Facebook! I'm not sure it can be done, but I'm interested to see if it can be.
