This week, I came across some things I thought I’d share.

First, for those who are a bit ‘Web 2.0 Illiterate’ we have: A Social Media Glossary! (I even learned something. What’s a Quantcast? Will I ever need to know? These and other questions answered…)

Secondly, an insightful opinion piece: Six reasons why Facebook is losing its way ; (Let the Betting begin! What is Xobini? This has some info.)

I have a take on this myself. Facebook is very reliable about some information, like, who your friends are, where you live, whether you’re male or female, your name, and even your social connections. But it isn’t very reliable about your preferences and your hobbies (and most of all, your needs!)

This means in layman terms that if you as a marketer or advertiser want to reach people, you will still be shooting blind. Is it better than putting ads on specific blogs, sites or networks? We’ve tested it out, and we have to say, inconclusive. The dividing between guys and gals, the fairly decent area network accuracy, the age information – very good! But better? Currently the ‘ad software’ on facebook itself is nowhere near what Google has, and competition is still lower (so we can’t say what your bang for your buck might be in the long run.) Jury’s out.

Also, for fun: Twitter Fail Whale Tattoo is Awesome, Kinda (And THIS. Plus a tons of nerdy tattoos. What is the ‘fail whale‘? You will have to use Twitter to find out.)

Have a good weekend, folks. We’ve got ‘secret projects’ to work on over here!
