I met Tamar Weinberg last week at a Mashable Meetup in Manhattan and she's one of my "Facebook Friends" and I occasionally see Facebook Friends Feeds updates from her - like the one I got tonight that said:

"…Tamar Weinberg is done writing that post that took eleventy billion years"

And I was thinking … what post would that be…. and then I found out it's …. Best Internet Marketing Blog Posts of 2007 which is the best links to a set of blog posts that I've ever seen - fantastic stuff, including posts that I've been looking for - like the The Big Juicy Twitter Guide  by Caroline Middlebrook which is made of a 7-part series on how Twitter has worked as a successful networking and productivity tool.

I saw the Top 29 Niche Social Media Sites (That Actually Send Traffic) by Andy Hagans lists great resources that aren’t necessarily being tapped into by many folks.

I'll need to spend several hours reading though many of those posts … 99% which I've never read.
