I've written this little hack that searches for people who travelled approximately along the same path as you. It looks at date/time and geo information in your photos and searches for people with similar photos.
@Suviko, I'd tried that at first, but the people who used the system didn't know the difference between their username and what they put into their url.
@_sarchi: thanks for trying it. I've fixed the layout problem for your resolution. Didn't understand your comment about being faster than Yahoo! though. I've made a gmaps version too if you're interested.
@purplewon2000: well, it would be good to know wouldn't it? The stalker becomes the stalked :D
