I think where we have sympathy for them is in that they solve a problem / are trying to provide value to people when craigslist has refused to do so. We dont like that innovation is being thrown out because it isnt in the controlling companies best interests. I understand that the right to control your software/hardware comes first (and would not ever change that), but it just sucks that this is the result in this case.
well, they should solve the chicken and egg problem of getting customers, tech problems are easy enough to solve, business problems are hard!
building your own social networking site that does everything facebook does and better is easy, get user's to sign up is not. trying to mine facebook for customers and data to jump start your site, well, that's not going to fly.
As I said, there's plenty of room in the market for competitors. I hate how poor the CL user experience is and how indifferent the company seems to their users. I'd love to see them disrupted. Nonetheless, my desire to see competitors succeed doesn't give the competitors the right to republish CL ads. Yes, it's tough to get around CL's first mover advantage but that's why successful innovators get paid the big bucks.
