In the midst of this debate, one kind of bias that has received much attention among technologists, as well as social and political scientists, is that in favor of “popular” sites. This stems from the PageRank algorithm, introduced by the Google founders in 1998. All major search engines today use similar techniques to identify important or prestigious pages and bubble them to the top of the results. To a first approximation, PageRank attributes importance in proportion to the number of links that a page receives from other sites. The algorithm is a bit more sophisticated than that, but this approximation turns out to be pretty good on average (cf., http://arXiv.org/cs.IR/0511016).

The notion of prestige based on link popularity is a proxy for other possible importance measures, such as traffic, expert judgment, and so on. Most people would agree that the use of prestige measures in ranking search results is a very good thing—indeed, it’s the main reason why search engines work so well and have become so popular. Moreover, PageRank is designed to mimic the browsing behavior of Web users. In the absence of better assumptions, we imagine that people follow links at random. PageRank then estimates the traffic through each site. It seems, therefore, to be just the right criterion to rank sites. Why worry then?

Snap’s “The Other Way to Launch” Contest
The contest works like this: starting May 15, 2006, and going until June 9, 2006, people will be able to post marketing/advertising ideas to the Snap blog. Those ideas will appear as posts on the Snap blog, along with a voting mechanism. All you have to do is a simple registration process (we won’t spam you nor rent or sell your name or email address) in order to submit an idea and/or vote. The higher number of votes an idea gets, the higher it gets in the launch plan. We’re going to create a marketing campaign using the best ideas.

As examples, some of the things we’re looking for, would include the reinforcement of “Why Snap is Better” differentiators, proper use of Snap logo, tagline, messaging, effective use of budget across a variety of media channels, guerilla tactics, viral marketing methods, etc.

The Reward
To make it more interesting, Snap is awarding $5,000 to the person(s) with the launch idea that gets the most votes from this community, AND $5,000 to the blog that is credited with referring the person with the winning idea. Please see contest rules on the Idea Submissions Page for more information.
