this is quite possibly bogus information. The article ( http://www.seomoz.org/ugc/link-tilte-attribute-and-its-seo-benefit ) says "I have yet to test my findings and would like to know if this technique will improve rankings or just improve my user's experience."
There's nothing to test. Google does not consider the title attribute.
This article says...
"Link Title Attributes: Think that you can simply add descriptive text to your "click here" link's title attribute? (For example: Click Here.) Think again. Back in the 1990s I too thought these were the bee's knees. Turns out they are completely ignored by all major search engines. If you use them to make your site more accessible, then that's great, but just know that they have nothing to do with Google."
I agree with this assessment and have seen others like it.
Matt Cutts made a similar comment about Google not paying attention to the title attribute, but it was in the context of images, which has alt tags (and anchors do not), so it's a little different scenario, kind of.
There is an argument regarding anchor titles indicating relevancy for the page it is pointing to. However, the blanket statement of "Google doesn't consider anchor titles" renders that argument moot. I can't find any definitive information that says otherwise.
