Quoted: I recall there was a study done at MIT years ago that looked at the number of founders and success of startups as measured by revenue 1 and 2 years after founding. It turns out that the success of your start up is directly correlated to the number of founders up to 4 and then it starts to decrease.

Andy Sack is working on his next thing.

Quoted: Andy Sack and Chris DeVore, who together founded Judy's Book, will announce Monday the formation of the fund, Founders Co-op. It will make investments of between $10,000 and $250,000 in new Internet companies.

Judy's Book decided to shift its strategy. Hope the decision pans out well! Yelp, however, has gotten traction in the consumer review space...

Quoted: Simply put, they out-marketed us. They managed from early on to make their customers feel loved. They were the first site (amongst Judy's Book, Yelp and Insider Pages) to focus on getting consumer photos up on their site. This was a very powerful marketing tool. They were aggressive at experimenting with parties and alcohol and building an offline community with their community. They made joining yelp a bit of a fraternity/sorority....in a good way. Their marketing efforts for a small company were better than ours.
