SpamRank
“PageRank distribution in your neighborhood: looks honest or spam? Our key assumption is that
supporters of an honest page should not be overly dependent on one another, i.e. they should be spread
across sources of different quality. Just as in the case of the entire Web, the PageRank distribution of an
honest set of supporters should be power law. Particular examples that raise suspicion when a page receives
its PageRank only from very low ranked pages (and then from a very large number of them); such a page
has little quality support that makes the fairness of the large number of low-quality supporters questionable.
Another example is a set of supporters, all with PageRank values falling into a narrow interval. In this case
the large number of similar objects raise the suspicion that they appear by certain means of a cooperation.”

Huffington Post
The Huffington Post is a massive-multi-user celebrity blog which started today. There are 300 bloggers all in all, including Diane Keaton, Warren Beatty, Walter Cronkite and so on. If one could expand all entries per day, this would make a nice print-out to read in the morning – if they keep up the pace, there will be dozens of posts per day. [Via Steve.]
Update; just some early nitpicking:
- Almost everything is about US politics (which is OK, except this doesn’t really fill a void in blogspace).
- The font is far too small. So are the headshots.
- There wasn’t anywhere obvious to contact the webmaster regarding 2.
- The terms are a little strange (no excerpts under law of fair use... when the use us commercial?).
- This doesn’t look too good with a Flash-blocker, which isn’t very blog-like.

Nielsen on Site Search Usability
Jakob Nielsen discusses how site searches which work different than the big 3 (Google, Yahoo and MSN) are bound to confuse users:
“Users are now forming mental models that they expect to apply across the Web, and even to their intranets. This is good. Existing knowledge of interaction techniques lets users focus on their goals, not the mechanics of operating the interface.”

Grokker Online
You might have seen Grokker by Groxis before as offline search application, but it’s now also available as (Java-powered) web app. Groxis is teaming up with Yahoo for this, Gary Price says.
