Was pretty much thinking the same thing when I decided to be more active here again. Checked the front page every few minutes (set on most recent and filtering just photography, because most of the digital / trad art stuff isn't really for me..) and it just remained basically the same pictures.. I can remember times when a "recent" pic remained on the first page for about 30 seconds because so many new pics were being uploaded...
Either these days are over, or the filtering is really screwed.. if the latter is the case, I can only second your appeal that somebody should do something about that..
Anyways, happy holidays to you as well!
And keep up the good work!
