As Facebook introduced their new controversial social plug-ins that seem to be taking off at great speed as 50,000 websites have now integrated them, LinkedIn has also introduced some major changes.

LinkedIn has now integrated new features to its status updates as it is now easier to share things from the web. Your LinkedIn status updates had been quite basic and limited up until now as they seem to be following the sharing idea as part of your status updates that Facebook introduced a while ago.

You now have more control over what you share and to whom as your status updates can now be shared with either everyone, a group, just your connections or a specific person. So you can be more selective about what you post and who you want to be able to see it. You can now include images and brief excerpts from a link that you want to share, again much in the same way you can do this on Facebook.

LinkedIn has also introduced its own version of Twitter's re-tweet feature as you can now 're-share' what one of your LinkedIn connections has shared. They will also be attributed as the source of the link you are sharing when you share the link yourself in your status update. If you just click on 'share' on the post you want to re-share you can post it to your group, send it to individuals or you can post it to your updates as seen here.

LinkedIn status updates and posts can also now be deleted much in the same way you can on Facebook with a little cross next to each post and status update that you can click on. So now you can get rid of any embarrassing typos or anything you may have changed your mind about sharing.

LinkedIn has also added a new feature related to company profiles. If you want to keep track of companies you are interested in on LinkedIn, you can 'follow' a company by clicking 'Follow Company' on the company profile of your choice.

This allows you to receive notifications by email or in your network about company profile updates, new job opportunities and when employees join, leave or are promoted in the company. You can edit these notification settings in the same way as your group settings.

So just as you re-tweet something on Twitter you re-share on LinkedIn and just as you follow someone on Twitter you follow a company profile on LinkedIn. I hope you're keeping up!
