WordPress is great but each upgrade or theme change is a bit painful because all customizations have to be moved manually and as long they are direct file edits, including fixes for not quite correct theme files.
So after all at least some of the updates have to be made as WordPress Plugins.
What’s cool about it is it’s anonymous both ways. I don’t have to expose my Google-ness to random visitors on the web, and if it gets annoying I can turn it off. Also, and most likely to be actually useful, people I actually know can go to my blog, check my status, and ping me if I’m around, all without downloading a client. On their end, Google is just running a web browser session for them. They don’t even need a Google account.
