The best thing about glowhost is the support. They are great.
And there's also active forums and some walk through like web hosting offers section (though a bit outdated).
I got in on the 5/month plan (they always have some kind of special). My only gripe is not true root access (in ssh) and that my resources are more limited than I'd like, 512mb ram, 1% of cpu.
Not sure about complaints about drupal and mediawiki. Their installer will automatically install both.
