I am always looking for really fun and cool things to organize my gazillion contacts on Google. It would take years to do this accurately.I found a good way to add additional information to them without spending a very long time going through each and every one of them. Rapportive, according their website shows you everything about your contacts right inside your inbox.
You download the application and in your Gmail, each new email you open will give you all the sender's contact information including picture and social networks it belongs to. This gives you a chance to connect on a couple different levels or just to get a better feel of who you are working with. The website describes Rapportive free relationship management for your email. You can immediately see what people look like, where they're based, and what they do. You can establish rapport by mentioning shared interests. You can grow your network by connecting on LinkedIn, Twitter, Facebook and more. And you can record thoughts for later by leaving notes. What I like the most, it keeps you and your social networking extremely organized and streamlined. You also have the opportunity to add notes to each contact that will remain each time you receive an email from the sender.

The more I use it, and as my business grows, I am finding this application more and more. It is interesting and a little stalkerish (my favorite) to see what makes the person you just had a phone conference with tick, as you glance at their follow-up email. The also wonderful thing about it, the other person doesn't have to have Rapportive set up in order for your to have the reap the rewards of this great organizing tool
