You will have tough competition from i.e. Xobni. They are free to use, well integrated with Outlook and let you display LinkedIn info about every email address that you are dealing with. http://www.xobni.com/social-outlook
You have a good point. But the next thing you need to think of is:
- is Xobni really serving the market in an optimal way?
- Is there something we can do better?
To be honest I don't see answers for those two questions on their landing page. My first feeling was that it was like more complicated version of the "connect" button in Xobni.
