Is there room for another photo sharing service?
catone: My buddy Allen Stern (of CenterNetworks) said something recently in a podcast that I liked and is relevant here.  Paraphrasing, he said something like, "In New York City there are a thousand pizza places and new ones opening up all the time.  Many of them are successful and some of the new ones will be, too."Or, in other words, there is always room for new startups that do the same thing.  Just do it better or differently -- have better crust, better toppings, faster delivery, free breadsticks, etc.As you said, "there are always people who are looking for a better solution."  You just need to make it.
