As we add things under the umbrella [tag:ayatana] project it's becoming too meta and doesn't really mean anything anymore. - [tag:tips] also appears to be not useful. - [tag:linux] isn't being used for the kernel, but more as a "I happen to be running linux" tag. This was once [cleaned up][1] but it appears to be back, perhaps just symlink it to [tag:kernel]? I've checked the affected questions and they all have proper tags to the subprojects, which is better anyway, so safe to remove those tags.
