Not sure if it's a stackexchange thing, or just because the site is new, but I can't seem to find all the related tags for a tag.
E.g. https://gaming.stackexchange.com/questions/tagged/team-fortress-2 currently returns 1 result, but I know that there are at least 3 tagged with this on the front page alone.
It might be due to the fact I think people are detagging
team-fortress-2, I'm not sure.
Sorry if this belongs on meta-meta.
