I see there is a [dreamhost] tag. That's useful: I like to see what issues of [mediawiki] users are host-specific, because certain shared hosts can be quite painful.
I notice there are 200 questions mentioning HostGator and quite a few of them look specific to that host (or if not, they should be edited to reflect they aren't). Would it be useful to add them a [hostgator] tag?
Presumably there are other shared hosting services in similar conditions.
