Chrome has no add-on archecture so there's no way people can build a delicious plugin for it. The alternative is a bookmarklet, there's one for delicious: http://delicious.com/help/bookmarklets.

Google just released this awesome browser. They have a great comic strip walking you through what the big deal is about, which is a must read for web developers. I've been using the browser for half a day and it's been pretty rock solid for all the sites I normally use. Javascript is clearly MUCH faster thanks to the v8 engine, which I think Steve Yegge alluded to a while ago. I like many of it's different features, and think it's a great boost to the browser world as well as javascript, i.e. the NBL(Next Big Language).
