Maybe you didn’t know they were coming, but you’ve probably started to notice them in your email: LinkedIn endorsements. The LinkedIn blog reports.

Looking for social media statistics? One of the best aggregators of stats I’ve come across is The Social Skinny, which posted 216 of them not too long ago. Noodle around the site and you’ll find hundreds more — enough to season any conference call or presentation.
