Blog that covers Social Media tools and Social Media analysis

Good question. I know of no such blog, so perhaps there's a niche for one ;-)

But in case you're actually looking for info & opinions on social media tools, and not sniffing out potential blog niches, here are a few blogs that are tangentially related and occasionally mention social media tools and their usefulness to social media marketers:

• http://www.web-strategist.com/blog/
• http://forrester.typepad.com/groundswell/
• http://blog.hubspot.com/
• http://www.kaushik.net/avinash/
• http://www.marketingzen.com/online-marketing-blog
• http://www.readthis.com/
• http://www.ducttapemarketing.com/blog/
• http://www.communityguy.com/
• http://www.emerkirrane.com/
• http://www.tawheedkader.com/

Hope this helps.

Have you checked out the Hubspot.com blog? It's not strictly focused on social media tools, but it is a social media blog.

They also have a web analytics marketing hub that may be of interest to you.
