This brings up the larger posts-vs-pages discussion.
I edit links on pages all of the time. Why? because old web pages die and new web pages appear.
Consider the links on my Immigration page. Would Google see the addition of a new link to this page as a spam indicator?
What about DMOZ pages? They add links to existing pages all of the time.
What about links in dynamic portions of a page? Every page on The Tech FAQ is updated with a new link every time I make a post to the blog.
And how does Google determine what is a "page" and what is a "post"? We're not all running WordPress, there really is no firm differentiator between a post and a page.
What do you think?
