This TechCrunch article was written by the founder of LaunchBox, making it essentially a press release. When TechCrunch covers YCombinator demo day, they send a reporter rather than asking PG to do a writeup.
most of the company descriptions just sounded boring. I skimmed through most of it and nothing popped out as "oh thats interesting, let me read more about this startup" except for the one about self guided tours. I though that was pretty cool. When I go to Europe I would love to have a self guided tour of London or something. That would be great.
maybe they were just poor descriptions in general.....
