FYI, and I said this to Ken as well - I kind of think your reliance on a bookmarklet is a pretty big downer. Personally, I really, really don't like bookmarklets in general, but even moreso because I don't use a bookmark bar. I didn't use Instapaper, for example, until I found a good Instapaper extension for my browser. As it is, it really doesn't do a lot for me that just grabbing a bookmark doesn't, because I have to go out of my way to do it.
That said, we haven't put the chrome extension in the webstore yet because we haven't yet opened up the service for public signup. As soon as we do it'll be in the chrome store.
