I attended Lotusphere for the 5th time this year. It remains in my opinion one of the best technology conferences available.
I found it interesting that one of the main themes was on web 2.0 and trends. One of the things I realized is that I needed to start blogging myself, as I do think this is more than just a trend.
Web 2.0 - I'm not sure if I "buy" that concept yet. All of the technologies that are typically bundled into the "2.0" discussion have all been available for quite a while, so I don't quite understand how someone can just decide to brand a group of technologies that people have been using for years already.
