After 20 years or so, AOL Instant Messenger is shutting down. Not really a surprise. A lot of instant messaging services have come and gone. I still have an AIM account that is named after an FCC callsign I was granted in 2000 but no longer have. At the time it was easy to communicate with less techy friends and family and it was easy to use on Linux with programs like gaim.
I currently use it through a program called bitlbee and then interact with that through irssi.
While AIM is shutting down, I still have Facebook Messenger, Google Hangouts, and regular IRC on FreeNode. I also use email.
Remember ICQ? It's apparently still running and I think people are using it. Implementations come and go but there will always be a way to do instant messaging in some capacity. People seem to like that. Right now I am working on a more integrated and reliable setup for my Facebook Messenger+Google Hangouts+IRC setup so I can move between computers and networks and have everything move between clients. Yeah, that'll totally work.
