Since some of the top ranking search results are owned by competitors (such as Yahoo! Finance) it probably does not hurt Google to keep the visitors at Google by providing a bit more data in the search results.

Arts:
Also, Google changed their logo for Vincent Van Gogh today. You gotta wonder if the person advertising for that term is going to see a huge traffic spike and lowered ROI on the day.

If I were an aspiring artist who had a few bucks and was trying to promote myself today might be a good day to get some exposure. One of my friends is an artist and a while ago he got to meet Pablo Picasso.

Google Video:
Jeff Dean talks about how Google works. Although he mentions nothing about rotating algorithms.

Google Rotating Relevancy Algorithms:
being discussed at SEW forums in this thread.

[update: NickW pointed to this post, which states that currently there are 3 main Google relevancy algorithms and that they use Agent Web Ranking to check their positioning.
McDar & WM Community also have tools that search multiple data centers at the same time.

in the SEW thread PhilC also points to a list of current active datacenter IP addresses.]

This is SEO:
Greg Boser, known for talking straight about SEO, gets a mention in Wired.
Xan states that he views the article as short sighted. I was going to post on his blog, but I did not feel like signing into my .net passport to do so.

LEGOs Rock:
and now, so does Batman.

TV B Gone:
brilliant

Website Dating:
My Density shows first and second degree relationships between websites.

The interface could be a bit cooler and smoother (perhaps if they used a bit of AJAX and ensured the text was easier to read on scroll overs if they are showing a ton of data in a small area), but it looks like a cool idea. more info about My Density and even more info here.

A9 OpenSearch:
I saw this mentioned a while ago, but I think I forgot to link to it. Essentially it allows search results to be reformatted & reappear elsewhere. Robin Good has more about why he feels it is important.

Amazon Ads:

ABC of SEO:
Brad Talmir reviews The ABC of SEO. I too bought it and have read a chunk of it so far. Thusfar I have similar thoughts as Brad. Good for learning what the jargon means, but I did not like the occassional accusatory overuse of the term black hat SEOers.

Buying Links to Ban a Competing Site:
Rumour has it that with the latest Google update a few people have started in on this practice...buying sitewide keyword rich links to help their competitors get blacklisted...surely SEO is going to get a bit more ugly here soon ;)

Directory Submission:
150 directories for $99. Not that long ago the price was $30 so there must be decent demand.

I tried the 50 blog for $10 package for a few sites a while ago, but something about that price makes me feel like the service quality has to be limited.

Price points also help people associate a value with the service, so even if the service is decent the person doing it should charge more to make people think they are getting something of value, which generally appears not to be the case right now.

I do a good bit of directory submissions from time to time. I usually submit to about the same number of directories as that package except I do both free and paid directories. I do not mind paying for links because it means that the directory is more likely to have a functional business model and the links will not go away as quick.

Directory registration is exceptionally effective in MSN and Yahoo! right now.

Competition Equalizer:
other than having a different name what the hell does this software do that AdWords Analyzer does not? Wouldn't it have been better to release any additional AdWords related features as an upgrade to the AdWords Analyzer program?
