I was at web 2.0 last Thursday and Friday and had a good time. I've been attending web 2.0 since 2004 when web 2.0 was born. I remember because I was there right after George W Bush was re-elected. The mood at that time was somber disbelief politically and a sense economic opportunity elation (if that's a phrase). This past week was the opposite. Political relief, elation and awe over Obama and a real sense of economic sobriety.
That said, it seemed like it was business as usual...just slower with less enthusiasm. There's a real sense that hard times are upon us but hope springs eternal amongst the entrepreneurial crowd. People are still looking at starting companies and getting funded... which is good.
