Even the online service still exists though it's on it's last legs. Several months ago I logged onto my AOL account and tried some chatrooms. Vert few people in them. I mean vey few as in 5-10 in rooms that used to be full to where there would be 1-2 additional rooms created. Cities like Denver always have 0 users. Plus the few people in those rooms don't talk, like they are bots or something.
People moved on starting around 2007-2008 or so and AOL became a ghost town.
