Blogs are great; good for sales. Word Press is okay; I have two blogs on Word Press. I have heard that it is resource intensive. If you are going to do many blogs or use RSS feeds to the blogs, I recommend Blogs Organizer.

I do not recommend starting a link list. It was many hours of work to get it running correctly plus some custom php work, and I get perhaps as many as 5 submissions a day. However, now that it's been running for 3 years, it is good for sales and is easy to run.

I'd recommend a private tube site over a TGP site these days. I get lots of search-engine traffic to my tube site, and the users spend 5 to 10 minutes per visit. Only so-so for sales, though.
