Sex-tracking app Bedpost has offered up a round of beta invites just in time for a kids-today-and-their-websites! mention in the Washington Post. The concept is so close to something that has surely erupted a dozen times as drunken afterhours banter at MIT: If only we could monitor how often and how well we get laid, we'd be able to take nerd control over our sex lives. And Bedpost, even in its early releases, gets uncomfortably close to working as a sex predictor — if spreadsheets turn you on.

Each sexual encounter entered is infinitely taggable, permanently linked to one partner. (Alpha users have already requested multiple-partner support.) In aggregate, you can see when, with whom, and for how long you're typically having sex. The reward for postcoital data entry? A few perversely innocuous charts and graphs.

Even if the early adopters are loving Bedpost for its privacy features, what's missing for potentially heavy users is the ability to open up their data and share. Having sex may still be a private experience for some people — bless their hearts — but the act of finding more sex to have is so inherently social it's amazing there isn't a Facebook app for it. What happens when one can search for others on the Bedpost network who like it against the kitchen counter on a Tuesday afternoon with most of their clothes still on? Or receive SMS alerts when a past partner is updating his profile? The newspapers ought to fund this just to take down Craigslist once and for all.
