headline pretty much says it all. I just wanted to hint that (for me, at least) the search by tag functionality does not retrieve the latest post tagged. Right now, for example, searching for "Portal 2" tag does not return the DLC post.
Maybe this is to be confirmed by others, but I guess its some website problem.
Firefox 7 and IE 9 have this problem for me.
I use this feature to get to posts I know have been posted a couple of days ago, so I hope this is in fact a bug, not a feature.
