LinkedIn announced publicly that they are adding a great deal of functionality to their platform by offering a directory of applications. Applications allow user to extend the usefulness of their profiles and networks and allow third-party developers the creative freedom to leverage LinkedIns very large user base.

Facebook has used this strategy very effectively.

I believe this is not only a necessary step for LinkedIn long-term, it will make individual use much more powerful.

Some of the examples of the first round of applications include:

Work collaboratively with your network.

• Box on LinkedIn: Share files and collaborate with your network.
• Huddle on LinkedIn: Private workspaces to collaborate with your network on projects.

Share information and keep up to date with your network.

• Amazon on LinkedIn: Discover what your network is reading.
• TripIt on LinkedIn: See where your network is traveling.
• SixApart on LinkedIn: Stay up to date with your network’s latest blog posts.

Present yourself and your work in new ways.

• Google Docs on LinkedIn: Embed a presentation on your profile.
• SlideShare on LinkedIn: Share, view and comment on presentations from your network.
• WordPress on LinkedIn: Promote your blog and latest posts.

Gain key insights that will make you more effective.

• Company Buzz by LinkedIn: See what people are saying about your company.

If you are a LinkedIn user already, you will find lots more to do here. If you haven’t tried LinkedIn, now might be a good time.
