"I will not leak pagerank from my inner blog pages which will be too
weak to rank if I have on every one of them 6 outgoing links. That's
why I don't use sitewide links and you shouldn't too. Google this: how
blogroll can kill your pagerank"

So I Googled it but naturally with a skeptical mind as I always hear
about myths on this subject. Can someone please have a read of the
website I'm just about to quote and tell me if there is any truth to
it?

"If you have 100 external links on every page of your site, you need
loads of internal links to retain some (hopefully most) of your
pagerank, and make sure those people you give a link to on your
sidebar reciprocate.

If you can't get a reciprocal link, use nofollow, or stick them on
their own seperate page so they don't suck your own site dry."

Look forward to your thoughts :)
