Jimmy Wales/Wikipedia target the weakness of Google's PageRank

BusinessWeek notes:

People can contribute to Wikiasari [of Jimmy Wales] in one of two ways. The first is by enabling ordinary computer users to rerank search results. When a user performs a search on Wikiasari, the engine will return results based on a formula akin to Google's own Page-Rank system, which determines relevance by counting the number of times other Web pages link to a specific page, among other things. Unlike Google, however, users will then be able to reorder the results based on which links they find most useful by selecting an edit function. Wikiasari's servers will then store the new results along with the original query. When the same query is made in the future, Wikiasari will return the results in the order saved by most users.

IPBiz has noted some of the goofiness of Google's ranking system.

BusinessWeek continued: "I wish I could write a Google-killing project in three months, but it is going to take a little bit longer than that," says Wales. "We will have something up in '07, but it won't be very good or interesting. It will be a starting point for people to play with."
