Yahoo had rejected Microsoft multiple time, and they have contributed to open source community with projects like the YUI javascript library. What makes me wonder is that why are they not even making software on linux? If you look at their unix download page http://downloads.yahoo.com/?p=unix all of downloads seems not to be from yahoo. And from what i know (which i might be wrong), yahoo has no plan of even building software for linux. If you look at their messenger/IM client, they didn’t even manage to upgrade it for years or has no future plans for it.

If yahoo doesn’t notice yet, almost all the places where they are strong, people are starting to use the cheap laptop that run on linux (asus eee and likes), and more and more my friends are switching from yahoo to skype (which is good anyway).

I do know that they are not a software company and windows is still their biggest market, but if they supported Mac with their new softwares, why in the world would they leave linux when they hated Microsoft?
