DevShed and NoFollows

I have just been trying to figure out a question about devshed forums and was just wondering what people in SEO realms thought about devsheds use of NoFollows.

The one specific case (yes I am pulling this current page apart) that I am querying is the use of NoFollow on the title.

The current title on this page is "Search Engine Optimization" and this title links to http://forums.devshed.com/

What would be the benefit of using nofollow on links like this? (aka Why?)

The code is something like


I am just using this as a learning exercise (learn from the best?).
Where do you use nofollow, other that the obvious user submitted external links?

Also the link to http://www.devhardware.com/ in the top right uses NoFollow, why or why not would people do this?

A page can share it's PageRank with links. If a single page have two links, than PageRank is shared equally between those two sites (or pages). For example: If page A links to page B and C, than page A share it's PageRank with B and C.

But if one link from page A has command rel="nofollow" (for example to page C), than the other page will recive all the PageRank from A (B will receive all the PageRank from page A, and will not share any with page C).

So, it's all about PageRank.

More of this you can read in http://www.webworkshop.net/pagerank.html, and especialy in http://www.iprcom.com/papers/pagerank/index.html this site.

Don't try to manipulate PageRank too much.
