this website is as addictive as HomestarRunner.com itself, if not, more addictive. like, when I'm not watching a Strong Bad Email, I'm just constantly sniffing and finding stuff on this wiki. in fact I find it more addictive and interesting than WIKIPEDIA for instance. and that is thanks to the huge amount of dedication from the fans who are running this wiki (wherever you are, keep up the hard work.)
though I'd have to give HRwiki one negative however, and that is it doesn't load up half of the time (though you could use homestar.wiki in case if this happens. it basically caches links from the HRwiki, though some parts (like the image files) won't work.) so you can still browse and enjoy the HRwiki as long as possible. (and maybe watch a couple o' SBEmails along the way)
comb.io may not be an HRwiki, but i find myself stumbling across this site from time to time (mostly for Family Guy). it's also got a couple of Simpsons and Futurama clips if you're into that kind of thing.
