This is awesome. Made an account to thank those involved for doing this. FoxLisk for Member of the Year! If no such title exists, then Member of the Year for FoxLisk.
Got a few questions and comments, too:
1.

We use the same formula that USCF uses, and can been seen
here.
I was looking at the list of players ordered by rating, and I noticed that only 12 players have ratings below 1000. In general, the median rating of the SSPDB seems to be way above the median rating of the USCF (657 according to the Wikipedia page), so obviously there has to be
some difference in the formula you're using. Did you guys intentionally go for a higher median? Not really complaining, I'd just like to know for reference.
2. Would it be possible to have each player's Elo progress displayed in the "Recent sets"-lists? Right now it only displays the current, up-to-date rating. An example from Zgetto's match history:
Loss to Armada (1913) at Smash Attack (Match History) - 04/03/2009
Loss to Armada (1913) at Smash Attack (Match History) - 04/03/2009
Win over Armada (1913) at Smash Attack (Match History) - 04/03/2009
1913 is Armada's rating today and not back then, and of course his rating should have changed upon every win and loss. Right now I can find out a player's rating at the time of any particular tournament by seeing when the tournament was played and then checking that player's Elo History graph for the corresponding date, but that seems a rather convoluted way of doing things, doesn't it?
There'd be another benefit for this, too: the progress of a player's rating would be much more fine-grained. Right now, the rating changes of the graph only reflect what the rating was before and after a
tournament. Bringing it down to the accuracy of
sets would be great.
3. The ratings sometimes jump around too much, and in ways that don't make sense. For example, around the time of Smash Attack (May 3, 2009), Zgetto's rating was 1692 and Armada's was 1925. Then Armada drops one set to Zgetto (and wins two) and his rating drops over 500 points to 1408, below his opponent's. Zgetto also lost like 330 points from that clash. Shouldn't the net change of Elo in a match be more or less +/- 0? What one loses, the other gains? Right now it seems as though it's possible for both players to lose, and that doesn't seem right.
4. It'd be nice to have an option to sort the list of tournaments alphabetically as well as by date - makes it easier to check how many installments a particular tourney series has, for one. Also, if such information can be extracted from the files easily, it'd be cool to know the number of entrants for each tournament (and sort by that information, of course

).
