I’m asking because one of my primary annoyances is not having an all-in-one browser/IM/email client to usher ex-AOL users to once they’re ready to quit AOL. For years I’ve wanted to be able to say to them, “There’s this program named X that works just like AOL does, with instant messaging, email, and browsing all in one client, but it runs on a more modern layout engine, loads more pages the right way than AOL or IE does, and it’s safer to use and more enjoyable than AOL.”
Outside of SeaMonkey, there is nothing on the market that I know of that can replace not just what AOL has, but the way AOL combines it all into one client. I don’t think it’s a bad thing to just use Firefox and say, Yahoo! webmail and/or Outlook if you like, and to keep an AIM or MSN client on the computer for chat, but for people who have used AOL forever and like having all three tools ready-to-go in one browser, having a replacement for that would make it much easier for them to move away from AOL.
