BitlBee natively supports the following IM networks/protocols:
- XMPP/Jabber (including Google Talk)
- Microsoft MSN Messenger
- Yahoo! Messenger
- AOL AIM
- Twitter API
- Set up a Bitlbee to micropub protocol and you could post notes directly from chat. — gRegor Morrill
- Webmention notifications in bitlbee might be easy to set up, but maybe just direct IRC would be easier.
