I remember reading an article interviewing the del.icio.us founder when Yahoo first acquired the company. He said he was in talks with Google at the time also. Google told him they have plenty of idea guys and they just need more programmers. Yahoo told him he can run it exactly how he has been running it. I think large companies are starting to realize that the team is just as important as the product. Often times the acquisition deal includes the team… and sometimes the people who worked on a product are a more valuable part of the deal than the product itself.
