If you’re an affiliate marketer or network using Twitter, Facebook or Google+ (and honestly, if you’re not then you’re probably already obsolete), you need ThinkUp:

ThinkUp 1.0 and Software With Purpose – Anil Dash: “Today, ThinkUp is out of beta and available for free. If you have a presence on Twitter, Facebook or Google+ and know how to run a PHP/MySQL app on a web server (or on EC2), you should install it and get it started now. ThinkUp will collect all of your activity across these networks and give you great analytics, search and archiving for them.”

And here is Gina Trapani’s post (she’s the main developer and you should read/follow her work) on the 1.0 release

I’ve been running ThinkUp on my own personal server since the early betas a couple of years back and it has provided me with a wealth of information (and backups) simply not available anywhere else.

If you know the least bit about tech, you’ll be able to set this up on your own server.

Go do yourself a favor and learn/archive more about your social interactions.
