I host my personal projects on Google Code. In contrast to Github it lets you host files (especially important if not all your users have compilers or similar tools), and lets you have multiple repositories per project. Pretty much every hoster does two repositories per project - one for the main source and a second for the wiki. Having more than two is great. For example for work stuff I often have Android client and server as different repositories. But there is no need for them to have separate bug trackers or wikis - for an end user it is often hard to tell where an issue actually lies and having to copy issues between client and server side trackers is useless work. Github's issue tracker lacks being able to prioritise which is highly annoying.

The most annoying problem with Google Code is they refuse to have private paid for hosting - https://code.google.com/p/support/issues/detail?id=1829

Having all our employees create new Github accounts and doing administration there is a pain when we already do everything else at Google. I suspect paid project hosting would also help improve Google Code since there would be revenue behind feature requests and bugs.
