Rapportive is a free browser plug in (Firefox and Chrome) that replaces the advertisements in your Gmail sidebar with useful information about your contacts. You can see a picture of them, a bio, their latest tweets, Facebook and Linkedin updates and more. Even better, you can tweet and comment right back to updates that you are seeing in real time.
Rapportive started back in January 2010 and has hit the road running ever since. I’m not going to lie, I’m a bit of a junkie when it comes to logging in to Facebook or Twitter multiple times a day (more than I would like to admit) and I think it is so cool to see constant updates when you are in your Gmail.
Rapportive is very easy to install and only takes a few minutes. Once it is done, click on one of your emails and you will instantly see that person’s details in your right sidebar and links to their social media accounts.
