The Internet is full of plug-ins and random programs, some cool and some utterly useless. The Rapportive plug-in is definitely one of those plug-ins that falls in the 'cool' category. This plug-in turns Gmail ads in your inbox into an in-depth social media profile of your current contact.
The Rapportive plug-in pulls profiles from places like Facebook, Twitter, and Linkedin letting you follow or friend them all from the comfort of your own inbox. Check out a sample shot of the Rapportive plug-in above to see how all this works, or download the free plug-in for yourself.
