I just read about this site, InSpot, to anonymously notify your sex partners of your STDs (or as I prefer, sexually transmitted infections, STIs). Baltimore has not yet made the list, though many of us who have done research there know it ought to get its own hook-up. I'm a bit ambivalent about the anonymous sending of this info -- it seems like if you're sleeping with someone (or have been), you ought to be able to tell them this. Of course, if you're no longer sleeping with them and would prefer not to speak to them, this could be quite useful. Or vaguely passive-aggressive, depending on your interpretation.
Anyway, this concludes my friendly health advisory for the day. Go forth and avoid those STIs (though really, to tell or not to tell when it comes to HPV is another story altogether). We'll discuss HPV, wtf, at some other time.
