Fiona-the-would-be-wedding-crasher just tipped me off about this iphone app. Sadly, it's still in beta -- I really wanted to test it out.
Crash Corsage, theoretically, will scour The Knot, etc, for wedding dates, times and locations, plus details about the bride and groom (dumb stories about how you met + where you got engaged!) and make them searchable so people in the area can crash your wedding.
The moral of the story is: STOP POSTING YOUR SHIT ALL OVER THE INTERNET, PEOPLE.
