Since Linux support for the Humble Bundles is pretty highly publicized (including integration with the Ubuntu Software Center), should askubuntu implement a "humble-bundle" tag to address bundle related issues? It seems like there are quite a few humble bundle questions here already.
I feel as if this tag being created would invite fragmentation of games with other games. Maybe we should make a few subcategories of games that allude to being run in Wine,on being in the repos, without creating tags for every single game. This occurred on Arquade and via the actions of the cleanup processes, they have over 100 untagged questions. Since this invites anti-organization, we should not encourage creating tags for specific packages, except for the most important such as unity, USC, and Libreoffice, for example. Even then, we must still be cautious.
