I was really pleased when Terry started blogging

...rarely does reading a blog push me past my current range. smile

There's a promising trend of putting, on blogs or wikis (Terry has done an incredible job on the dispersive wiki, and Scott Aaronson built the complexity zoo), thoughts not quite ready for 'primetime' (nor any specific journal). It's quite an exciting development. It certainly changes the social dynamic: I can imagine that in the near future, the most important research institutions will not be individual research departments but online communities crystallizing around prominent scientists who happen to be terrific bloggers.
