Hi HN-<p>A buddy of mine recently told me to take a look a blippy.  I liked it, kind of.  In any case, I thought that this voyeuristic (or insane sharing) impulse could be put to use for dating.  What does that mean?  Well I think with user's permissions you could attach to their foursquare, blippy etc. (or use the api if one exists), gather up their recent check-ins/location data, and then compare with other people who have similar habits.  People with the highest matches could be recommended first etc. etc.<p>Yes/No/Already Exists?  What do we think?
