Ask PG: Startup Ideas We'd Like to Fund in 2010

In 2008 there was a great discussion ( http://news.ycombinator.com/item?id=250704 ) and a list of startup ideas that YCombinator would like to fund ( http://ycombinator.com/ideas.html ).

Do you think that it can be updated today? There are a lot more YC funded companies today.. maybe some of the problems are gone?
