It's like Yelp for people instead of restaurants, says TechCrunch, a somewhat scary-sounding combination, if you ask us. Recently making its beta debut, a site called Unvarnished lets any user create an online profile for a professional and submit anonymous reviews ... about anyone.

The site says its reviews "help you get the inside scoop on other business professionals, providing candid assessments of co-workers, potential hires, business partners and more." And while the comparable professional networking site LinkedIn also lets you leave reviews of past and present colleagues and co-workers in the form of recommendations, LinkedIn's reviews are not anonymous.

Unvarnished's About page states that "to help reviewers be honest and candid in their reviews, Unvarnished obscures the identity of review authors. This lets reviewers share their true, nuanced opinions without fear of repercussions."

Candid or defamatory? By keeping secret the identity of review authors, who's to know whether a negative assessment is coming from a past client whose project you screwed up, or Bob from Accounting, whom you screwed after the office Christmas party? No fear of repercussions doesn't sound like a great thing, necessarily.

But Unvarnished says they've got it under control with Reviewer Authority scores: Other Unvarnished users can rate the quality of an individual reviewer's submissions, resulting in a badge that is attached to each review by a given reviewer. There are five available badges: new reviewer, novice reviewer and three levels of "trusted reviewer." Trusted by complete strangers! Sounds fair, right? Anonymous Internet users anonymously rate the quality of other anonymous strangers' anonymous, possibly candid and honest, possibly slanderous, reviews of other individuals. Phew, thank goodness for that.

And the best part: the Internet never forgets, and neither does Unvarnished. Once your profile is up, it's never coming down. Every post, once you claim your profile, is there to stay. When TechCrunch writer Evelyn Rusli asked Unvarnished co-founder Peter Kazanjy if users would ever getting the option of taking down their profiles, he was succinct: "No, because if we did that, everyone would take their profile down."

Damn right we would, and we can't help but feel like services like these prey on our vanity-Googling generation, unable to resist the morbid curiosity to find out what strangers think about us. Unfortunately, this isn't just Hot or Not for grown-ups, and your morbid curiosity can deflate more than just your ego; it can also do a number on your online reputation, a concern even for those us who regularly attach our bylines to tales of sexual debauchery and drunken mistakes. After all, the story of the time your grandparents caught you having sex in their antique rocking chair is something you chose to put out there, for better or for worse. But you and I both know that it's possible to be a total basket case on evenings and weekends, yet totally kill it in the office, climbing that ladder with gusto and finesse. We just don't want the rungs sawed out from under us because we once forgot to return Psycho Suzy's clipboard and she's been plotting her revenge ever since.Unvarnished lets your colleagues review you, anonymously.

TechCrunch's Rusli has the same concern that this service can quickly turn into a "digital burn book" of sorts, and makes a good point when she says "Theoretically, a community of professionals has more scruples and ethics than a group of 17-year-olds," the key word, of course, being "theoretically." What easier way to test one's professional scruples and ethics than by putting a promotion, a raise or a livelihood on the line? Dangle a big enough bonus in front of someone's face and the office turns into a high school cafeteria food fight, with insults, insinuations and accusations (true or not) hurled every which way.

Still think services like Unvarnished will do more good than evil? Check out some of the barely comprehensible, savage rants on almost any website that allows anonymous comments. Do you want Max the Misogynist commenting on your managerial competence?

What do you think: Are review sites like Unvarnished a useful professional tool, or a disaster waiting to happen?
