The first popular online web messenger.

There really is nothing much to be said for the technical features of Meebo. It came, it was fun, people used it.

On the community side, the Meebo team is a quirky bunch. If you have a Meebo account, you can see their blog postings everytime you log in.

There's also a community chat room/group style feature called Meebo Rooms but the content is really nothing special to be said of. Many of the features are also underused so as of this writing, it's more of a neat side feature to an online service that provides users with what they want: A free no download online web messenger that supports numerous web services.
