My 2 cents:
For the listing of new games, I would think the ability to filter and sort would add an element of bias. One person reads a new story and rates it a 3, so everybody else filters it out and never sees it. Or everybody just gravitates to their favorite writers.
Which is not to say these things don't happen already. But the new story list is the one time all stories are presented equally, so the emphasis should be in letting people find these stories and coming to their own conclusion, before we're filtering them out of our views because of someone else's ranking.
On the other hand, and option to find games created so far this year might be useful.
Again, just my thoughts. This and a couple bucks will get you a cup of coffee.
