IMO messenger app dropping support for third party services like GChat, AIM, MS Messenger

imo.im blog Discontinuing support for all third-party messaging networks

I use IMO on the Kindle Fire, but now I'm not sure what to replace it with. I primarily use it to connect to Google Chat (Talk/Hangount, whatever they are calling it these days!) My wife also uses it on her iPad, but I just realized that Google now has a Hangouts app, so I'll just tell her to install that.

I use IM+ for my Windows Phone, but its not the most elegant app.

Anyone have suggestions for alternatives?
