I had an intriguing demonstration yesterday from social CRM vendor Nimble. Since “social CRM” could mean just about anything, it’s important to explain what Nimble actually does: it combines traditional contact management with automated access to social media information about those contacts. That might not sound like much, but in practice it’s pretty darn slick. Here’s how it works. Say you’re selling a product related to, oh, circuit boards. For the users themselves, Nimble has one more advantage: its lets them stick with familiar communication tools.
