Wow, that's a ton of companies compared to "back in the day".<p>It'd be interesting to have a nice summary of recent batches and where they are to see what kinds of ideas have gotten traction. There are some there that, from the one sentence blurb, don't sound that interesting, but I think the YC folks and the people they invest in are smart, so there's got to be something there.<p>I'm personally interested in seeing what BookTrope is doing, as it's in a similar space to my own LiberWriter.<p>Good luck to all of them!
