How Would You Improve LinkedIn?

After bursting onto the scene to become the most popular professional networking site, LinkedIn seems to have gone the way of Delicious, making few updates to their platform and user experience, even as new technologies and user behaviors have changed. Meanwhile, Facebook is consistently making improvements that move in on LinkedIn's territory.

Don't get me wrong -- LinkedIn is great. But it could be a lot better. Here are a few ways they could do it:

Improve (HTML) formatting options: Most resumes exist in bullet form, so why doesn't LinkedIn give users the option of creating HTML formats in the job descriptions? Seems like an easy addition that will lead to cleaner, more organized descriptions of users' work experience.

Choose which connections receive updates: Facebook has privacy options for which friends see which updates. LinkedIn should have the same. The most obvious reason would be during a job search while still employed. Broadcasting to your network is often a better option than messaging your connections individually, but the problem with the current setup is that ALL your connections see the broadcasts, including your current colleagues. Maybe this is solved with an "I'm looking" indicator that is only seen by the people you want to be able to view it.

Non-recruiter job postings: I constantly hear about jobs via word of mouth, yet LinkedIn doesn't make it easy to share these jobs on their site. People are on LinkedIn for a reason -- to network. And the best people to have in your network are the ones sharing jobs not just at their own company, but at other organizations. Sure, recruiters and HR people can post jobs, but why not create an aggregator for jobs posted by people in your network that lives separately from the more formal "Jobs" section populated by recruiters and HR? You may not be able to apply directly, but at least you know who in your network can connect you to the right people.

Social links: Currently, there is a max of three links that can be part of a user profile, and a lot of people use at least one of those to link to their presence on another social networks.  With social networks like twitter and FriendFeed playing a larger role in how people market themselves, LinkedIn should provide an easy way for users to display their online presences.

That's where I would start.  What would you do to improve the LinkedIn experience?
