Back in June Microsoft posted a new case study highlighting the work IdentityMine did for InfoSpace in delivering a new set of toolbars built in Silverlight. The entire study is a great insight to InfoSpace's business and how it has morphed since it was first founded in 2006. By creating toolbars that had real and valuable functionality for users, InfoSpace was able to create a successful targeted advertising business. IdentityMine contributed development and integration efforts to ensure that design fidelity was maintained throughout the project while still delivering on the key functionality required by the client.
On a separate note, it seems that Microsoft has recently revamped their Case Studies website. Overall it's a great site and presents a very nice interface for sharing success stories with partners. From the case study page you can email a link to the Case Study or download a packaged Word document to pass around.
In addition Microsoft has added a few Social additions to allow customers to add content into popular services such as Delicious, Digg, Windows Live, reddit and StumbleUpon.
