I interviewed with OpenTable in 99/2000. I got into an argument with their tech lead during the interview and sadly was not offered a job! hahaha I will always remember OpenTable because apparently they had built a great system on Java and Oracle (all very cutting edge at the time) and it worked great. However they were switching to Microsoft's DNA platform because they had a VC who was in bed with M$. Nice! I liked their CEO and I'm betting that their success is almost entirely due to leadership, not technology or lack of competition. Also, while I'm sure there's room for competition, their kind of business is heavily tied to relationships which they have no doubt cultivated for many years. An excellent and well-earned high barrier to entry.
