I read that Yahoo joins Linux foundation:http://www.meegoexperts.com/2011/04/yahoo-joins-linux-foundation/
I wonder if they will make a Linux version of Yahoo messenger? (would not be necessary with Gyache Improved then):http://messenger.yahoo.com/
Yahoo had a old version for Linux before:http://linux.softpedia.com/get/Communications/Chat/Yahoo-Messenger-2.shtml
But the latest is only for Windows, Mac and iPhone.
