They say it's important to make a good first impression, but that's cool, new subscriber, you just go ahead and keep picking your nose while reading this. Helping the e-you do a better job than the real: Reppler.
From a security & data analysis vet, Rep'll take an objective look at your FB account, flag it for potentially incriminating info, and offer an overall analysis of "how others may perceive you", as photos of keg stands can so easily be misinterpreted. Grant it access and Rep'll comprehensively scan for "inappropriate content" everywhere from your wall to your newsfeed, going back as far as you wish, and sending you an email as soon as it detects any "derogatory language" or "adult content", so...no F/X original programming?
Taking things next level, they'll analyze the "tone" of your posts (frequency of "positive" vs "negative" verbiage), show the sources that provide the bulk of your wall posts, and even visually break down the times of day during which you're most active, not an option for your sex life, as that pie chart would require you get some.
They'll also alert you to any info that may be vulnerable thanks to Facebook's byzantine security policies, 'cause anyone who's had their identity compromised can tell you it-snot very cool.
