I’m a little late in posting this, but as one of del.icio.us’s 2 million+ users, I have to do my part in spreading their PR gospel about their new Firefox add-on. The biggest enhancement is that it’s easier to sort through all your tags and bookmarks without going to the del.icio.us site. My del.icio.us page is here; if you’re on it, let’s connect.
A year from now, I’d be surprised if Twitter‘s still in wide use, but del.icio.us keeps getting more valuable the more you use it. Also be sure to check out cloudalicio.us for tag histories; it’s great consumer research to see how people label tag sites over time.
