I was going to put together a SEO blog list as well, but why bother when fantomaster has the goods right here:
SEO/SEM Blogs (I just added his link on the bookmark page)
A few more things I added:
WorldInternetSummit Forum – Marketing/Business Forums
PookMail (temporary email address – seriously, it’s for 24 hrs! ) – Email Category
Extension Mirror – Computer/Tech Category (tools page)
That’s it for now, enjoy!
