It used to be that sites were automatically added to the affiliation list as long as the submitter was a member of TYWC. However, then I found out that search engines penalize my site if I have links to sites with poor or no page rank. I won't go by page rank in determining affiliation, but I will go by content and design; that is, if the site has good content and is designed well, I'll add it.
Cheat your landlord if you can and must, but do not try to shortchange the Muse. It cannot be done. You can’t fake quality any more than you can fake a good meal. — William S. Burroughs
