You never know when a stranger might harbor strikingly similar characteristics & interests -- especially if your mutual interest is not having strangers walk up to you and tell you about their interests. Find similar folk digitally instead of psychotically, with Like Ourselves.
Just beta-launched by two Londoners -- one of whom decided "throwing his life savings at an idea was far better than actually having a life" -- Like's a Gmap-powered web & mobile service that alerts people to anyone nearby professing like-minded enthusiasms, from need-based, to cultural, to professional, to product-based, to a shared love of crassness (base-based). Some current categories, from typical to possibly mad:
• Start-up Networking
• Media and Journalists
• French/American Ex-Pats
• Flatmate Seekers (already easy to mark by the chairs strapped to their backs)
• Spontaneous Date
• Socially Awkward
• "Graduated. No job. Alcohol IS the answer."
• Ladies Who Hunt in Packs -- presumably younger ones, as the cougar's a solitary predator
The mobile also packs a "super-high function" feature whose icon goes from orange to green when an interest-match is in the vicinity, and of course displays that person's profile pic -- because when it comes down to it, we're all really just interested in someone who's good looking.
