Exoplanets.org have a new, interactive table system for their exoplanet data. You can sort, filter* and search the tables for orbital period, mass etc. The tables have hot links to publications and orbital data, which makes a Celestia fan like me really happy. There is also a plotting page, where you can graph statistical features of known exoplanets. Okay, so I'm a geek and nerd and find this sort of stuff cool.
* Which I can't make work eg name = "WASP-2 b" should return the planet WASP-2 b, but the filter just sits there and looks at me. But for some reason name > "epsilon" sort of works
