Just got back from Linux World 2007 at the Moscone Center. This is my first trip to Linux world and I was impressed. I saw a huge breadth in the crowd. Got to meet some sisters from church ministries to CEO's of companies asking if I had a CEO opening in my company :)
Technology wise the companies that were taking center stage were the usual suspects Intel, Oracle, IBM and HP. Vmware also got a lot of attention and was one of the more popular booths. Amazon had a booth showing off their web services stack. There were quite a few backup solution companies. O'Reiley was a very popular booth. Overall the conference had a very good mix of companies covering a broad spectrum.
