Nice list. I would argue you left off the awesome Conductor blog [disclosure: I work on the Conductor blog ;) ] Bookmarking lots of these!
Conductor also has a this little known tool for rankings or something like that:)
I like Usabilla for UX insights also. disclosure: I don't work for Usabilla:P
Wonderful collection! Thank you :)
Excellent list despite my blog not being on it. I know that being opportunistic is more popular than not but sometimes swimming against the tide is better in the long run. IMHO it's important that more SEO blogs speak out against controversial Google practices. Just getting penalized all the time and begging for forgiveness is pretty humiliating. So teaching you readers only this slaev-mentality isn't enough to make good SEOs.
