The semi-official Litecoin Slack is available at http://someguyslackinvite.herokuapp.com
We have a tip bot, an IRC bridge, and soon a Telegram bridge.
I like that chat, too bad there is not that much activity. The Bot is cool though, since it always links new threads. Do you think it is possible to make new threads on litecointalk.io appear there as well?
There is also a telegram group with many of us in the room http://telegram.me/litecoinCharlie is in pretty frequently and many devs.
