PubSub introduces Link Ranks

Pubsub has introduced a new feature called LinkRanks. From the about page:

“Link ranks are our way of measuring the strength, persistence, and vitality of links appearing in weblogs. When PubSub reads a new weblog entry, we pull out any URIs we find and attach them to the entry in a separate field. This allows our users to include domain names or linked file types when creating subscriptions.”

“From this set of URIs, it’s easy to find the most popular domains. Link ranks take one more step and calculate scores for each linking site; domains are then scored based on the values of the sites that link to them. The theory is basically that these are the links you’re most likely to click on, if you read a weblog at random.”

“Unlike Google’s PageRank system, link ranks are not iterative. Rather, we base link ranks on a simple formula that only looks at local links – links which are within one or two steps of any target site. Also, it’s important to note that we only look at links which are in weblog entries – we don’t read any of the other links on the page, like the side bars or blogrolls.”

Interesting. You can try it out for yourself. I checked out my domain for today and it went up over 10,000 “points” from yesterday. Yikes!! I like this new feature, even though it’s more fun than useful (for the time being, I suppose).
