I recently read a document by Dan Raine outlining the plugins he uses and the reasons which might change the way I do things a little bit. They include:
pubsubhubbub - to increase indexing speed.
SEO Ultimate – might be quite the update to the seo pack I currently use and even replaces pretty link as well as adds some awesome keyword auto-interlinking features.
WP No Category Base
RSS Bomber - I suspect this is the “affiliate” link he was going after in his pdf. When copying the pdf link, it gave me the actual text instead of the url it was pointed to… so if you click this link in my post and buy the plugin, nobody gets the affiliate commission. He probably should have done it in HTML so I could have copied the actual link from him!
