Related stories IMs a mixed blessing IMs are intrusive, private Since July, consumers with the new Microsoft MSN Messenger service have been intermittently cut off from messaging America Online friends and business associates - even after entering valid passwords for AOL's own Instant Messenger, or AIM, service. I can never tell who's going to be available to what program on any given day of the week.
Instant messaging allows communication faster than e-mail but more personal than a chat room.
Two or more friends using compatible IM programs can connect instantly to exchange small talk much like they would in a phone conversation, as well as trade work files, graphics and other items of mutual interest.

Behind the scenes since early July, software developers at Microsoft have been working overtime to find new paths to access America Online clients, posting program patches and updates almost daily. Meanwhile, programmers at AOL, the world's largest Internet service provider, have been working just as hard to keep AIM clients inaccessible to non-AIM applications. Discussion forums across the Internet, meanwhile, have lighted up with people taking sides in the electronic melee.
