“Hi, my name is Jonathan, and I am an oversharer.”

That’s probably how I’ll introduce myself when I call to order the inaugural meeting of Social Media Anonymous (“SMA”), the 12-step, self-help organization I plan need to launch for me and all the other location-obsessed citizens of the mobile/social Web.

What’s the issue? Where’s the concern? Why the intervention?

This notification I received from Foursquare says it all:There you have it. Apparently, I checked in so many times within a short while that Foursquare awarded me with its Overshare badge. In one brilliant stroke of communication, Foursquare mocked me for my check-in addiction, rewarded my obsession with (yet another) badge, and actually dared me not to brag about it!

I’m somewhat relieved to know I’m not alone in my check-in fixation. Foursquare conveniently lists my other friends who’ve also earned the Overshare badge. How very social of them.

Of course, I’m not naming names, but I know you’re out there – in NY, Chicago, DC, Paris, Berlin, Madrid — and you know who you are (BF, AR, FM, AD, BK, MC, PC, WC, CZ, SA, CH, ES, SS, GK, VL, LA).

Like they say, the first step toward solving a problem is admitting that you have one.

I think I’ve shared enough – for now.
