Today we're announcing many more ways to interact with your network on LinkedIn. Whether it's a new way to create projects and collaborate, share information, customize your profile, or gain key insights, the new LinkedIn Applications deliver.

Nine applications were rolled out and all are business oriented, (no "games", etc).

WordPress blog feed integration - pull your feed into your Linkedin profile, or only pull in posts tagged with the word "Linkedin". I set this one up in 1 minute with no problem

Other apps include "Company Buzz" - find out what people are saying about your company. Google Presentation and SlideShare Presentations integration. Reading List by Amazon, (self explanatory). My Travel by Tripit.net, Huddle Workspaces by Huddle.net.
