Matthew Gray's BGG Tools

I wrote an XML API to BoardGameGeek. I've written some tools, some of which use that API, but I thought it would be good to collect all of those BGG tools I've written in one place. Due to recent changes in the XML API, many of these are broken. I'm fixing them as I get to them.
BGG Mobile
An extremely minimal interface to BGG for use on cell phones and other mobile devices. When you're in the store and you see a game that looks interesting, it's a quick way to see what BGG thinks. still works
Justify your Game Collection
A piece of humor/analysis explained on my blog by which you can calcuate how large of a game collection you can justify. Strictly speaking, this isn't BGG related, but I'm listing it here anyway. still works
BGG Collection Overlap
How much does your collection overlap with someone elses? (see this BGG thread for discussion/explanation) fixed

The opposite of the preceding one. What does A have that B doesn't? (see this BGG thread for discussion) fixed
