Switched from Skype to Discord for gaming. No regrets.

The unofficial API community is also really great, and there are a plethora of libraries to choose from to get something working quickly.

Lots of support for Discord here on HN.

I saw some posts mentioning that a relatively large project had switched to it for support (Reactiflux http://www.reactiflux.com/ ).

Edit:googled the project

I'm pretty impressed with it too. Nice UI and good functionality.
