Yet Spock brings new approaches to search engine optimization that I anticipate will become a model for other sites, and it offers its own benefits for users to manage their online reputations, so it's one invite worth accepting, if just to see how it stands out.

Spock's core is a people search engine. Search for Guy Kawasaki, for instance, and the first listing that comes up provides information and links about him culled from various sources like his blog and LinkedIn profile. There are three hooks for what makes Spock different, even if the elements themselves aren't unique on their own: tags, profile aggregation, and reputation ranking. We'll explore how they work together to make Spock one of the more exciting sites to watch early this year.

Tags

The top of every profile entry includes tags. Tags on my profile include current and past job titles and companies, some basic biographical information ("from Mamaroneck, NY"), general professional categories ("search engine marketing," "emerging media"), and a few of my favorite TV shows ("likes 'Arrested Development'"). When I claim my profile, I can choose which tags are relevant to me, and those that aren't disappear.

Other Spock users can contribute and vote on tags too. If most of my Spock contacts know me for my search engine marketing work, they can vote on that tag and it will rise to the top of the profile. Considering the value tags have in search engine optimization, Spock is empowering its users to take care of a lot of the SEO for them. To balance that, the Spock Robot also votes. It even has its own profile, and its tags show how people have mixed reactions; some contributed the tags "hates privacy" and "finds way too much information," while others call it a "cute search engine spider."

Profile Aggregation

There's no shortage of profile aggregators that aim to help people consolidate their online identities, and this field should explode this year. What makes Spock a bit different is that its robot scours the Web and tries to group the profiles together, generally based on one's email address. Once you claim your listing (or multiple listings if needed), you can then select which profiles to add or hide.

Reputation Ranking

Whose opinion matters more, that of a Spock user or the robot? If the user has done anything on Spock, the human wins. That's because of the importance of Spock Power; the most active, trusted users have a greater say than anyone else. The robot's Spock Power score is a lowly 1, while heavy users have scores upwards of 1,000 (Spock co-founder Jay Bhatti has the ridiculously high authority of about 270,000, but I'm guessing he spends a little more time on the site than the average user).

It's rare to see a site adopt reputation into its algorithms and technological backbone. With Google Adwords, for instance, a click from one user is just as meaningful as a click from another. With digg, the number of votes and the rate at which they're entered determines what climbs the rankings, though a regular digg contributor who is active within the community will find his own submissions dugg more than others. With Wikipedia, anyone can contribute to or edit articles, though active contributors implicitly wield more authority (a select few have added authority for policing the site). With eBay, reputations matter, but among the larger community of buyers, the highest bidder wins an auction, not the person with the best reputation.

Spock takes a completely different approach, where it decides on the person's reputation, and the community then validates it. If Spock's robots are right, then why not expand the model? It can serve as a heuristic, a time-saving rule so people don't have to spend much time judging each other.

Then again, it does fly in the face of some of the democratization of media. It's not one person, one vote, but rather an aristocracy of sorts. The reason it can work on Spock is that with people's profiles, it's expected that the profile subject has the final say, while those with higher reputation scores will presumably want to only engage in actions that will increase their reputations.

Spock will still have the challenge of overcoming the "not another" reaction to its invites, but regardless of how well it does that, its model will likely spread. Maybe then the robot can earn a higher Spock Power rating.

This commentary is insightful. I recommend it to others.
