WikiMe answers the eternal question--Where am I?--by listing all Wikipedia entries for your location.

You know the saying: Wherever you go, there you are. WikiMe tells you exactly "where" you are from a Wikipedia perspective, listing all the entries that are related to your current location (or any postal code).

Actually, it lists only those entries that have been geotagged, so there may be some gaps. But even so, this is a killer tool for travelers. Imagine strolling the streets of Paris, Seattle, or even your own town, discovering interesting and potentially unnoticed landmarks as you go. Just fire up WikiMe and presto: Wikipedia entries pop up in order of proximity, complete with thumbnail photos when available.

By default, WikiMe uses a radius of 10 kilometers, but you can adjust that using an onscreen slider. You can also choose the maximum number of articles WikiMe should search: 25, 50, or 100--handy if you're getting too many results for a given location, or too few. For any Wikipedia entry you view, you have the option of seeing the location on a map, viewing nearby photos (culled from Panoramio), adding a bookmark, or even emailing the article to a friend.

Just two gripes. First, postal-code searches didn't work without also entering a country code. Um, what's a country code? ("US" did the trick for the U.S.) Second, if you run a search using a postal code, WikiMe can't return to location-aware searching unless you exit and restart the program.
