Web Page Strength & Importance

I came across backlinkwatch.com while searching the web. This site gives you all the links pointing to your site [back links]. Of course Google will do that as well, but this site provides two other pieces of data. First, the site indicates if the incoming link has an attached 'rel=nofollow' tag to the link, indicating that no page rank is passed with the link. Second the site shows the total number out going links on the page that contains your link. The more links on a page means that a smaller percentage of Page Rank [PR] is passed in each outbound link. The site found 5,158 backlinks for interfacebus.com. From the Back-link report I found tagurls.com which ... hmm, not really sure what it's telling me. But I found seomoz.org which gives an indication of page strength [SEO site]. interfacebus has a page strength of 6/10 per their report. Than cloudalicio.us was found which shows the number of tags [links?] occur over time on del.icio.us. Also checked out Technorati, guess they track blog activity.

Then I found this one http://www.usa.gov/webcontent/reqs_bestpractices/laws_regs/copyright.shtml.

Hmm, while interfacebus.com was rated 6 of 10.
