What the hell is a blogroll anyway?

A blogroll is a list of links. Generally blogrolls are part of a wordpress installation. A default installation will have a Blogrolls section.

This is where WordPress site-admins can place link to sites that they want to promote. Sometimes they want to promote their friends and relatives.

And somethimes they have several thousands pages indexed by google which you would do well to link from.

Someone with enough nouse to be using WordPress in this way would probably have experimented with various ways of making money from their website.

This is a good thing. These people have blog which they know the value of.

And know. Without question. That a coupla hunnert is a damn good price for dropping a site-WIDE link to ALL your domains. Innit.
