My friend, Kim has a great video interview out talking about SEO and Usability. Kim is a great proponent on ensuring a website is usable once a visitor lands there. As she says there’s no point in being number 1 in the search engines if visitors can’t find what they’re looking for on your site.
Kim also talks a little about the start of Cre8asite Forums, my home away from home. It’s a great interview and well worth a look.
