ug, do not waste time on sitepoint, wickedfire, or the like. seobook, seomoz, seroundtable.com, distilled.co.uk, wiep.net, wolf-howl.com, rosshudgeons.com, and citationlabs are all more worthy of your time. Read The Art and Science of SEO and attend to Mozcon in June and you'll be on the right track.
I don't know about Sitepoint for SEO, but I did like that one topic I linked to. I actually learned a substantial amount of my XHTML/CSS knowledge from Sitepoint (back in 2004-2005), so it's not all bad. :)
I like seobook and seomoz, and I'll check out the other sites you mentioned. Thanks!
