Here are some of ways I believe LinkedIn can update their site to become a more integrated part of my online life:

1. Make it easier to “friend” someone – I don’t know how many times I’ve had to go fishing through Outlook for  an email address to friend I know really well like my sister-in-law.

2. Better integration with other sites – Lifestreaming is coming to a laptop near you (See FriendFeed, Socialthing, etc) .  LinkedIn could take a lesson from Plaxo on how to connect with people’s lives.  It would be nice if I could easily import my blog posts, photos and other content into my LinkedIn profile.

3. Standardize status updates – Their 98 character status update is pretty short for people familiar with Facebook and Twitter.  It is also challenge to use a third party site like Hellotxt or PingFM to push your oversharing to LinkedIn.

4. Encourage greater use of their API – Much of the success of sites like Twitter can be attributed to the third-party applications that use the API to pull and add value to live data.

5. Better RSS feeds -It is nice to have LinkedIn feeds at all.  I can, however, imagine an infinite number of permutations for RSS feeds by company, region and education.

LinkedIn will continue to be a key part of the social media ecosystem.  I just wish it were more connected.  That is the point ofsocial media after after all?
