Spring 2013 has been an exciting time for LinkedIn and its most loyal users. Major profile changes have occurred, drastically altering LinkedIn’s look, features and functionality. As one of the major players in the social space, these changes prove that LinkedIn aims to stay current and relevant with the web’s most savvy.

LinkedIn Tagging

Those who regularly post updates to their professional profiles will appreciate the newly added “tagging” feature. You can now tag other users and business pages when you post an update.

LinkedIn Professional Portfolio

A much-needed (in my opinion) upgrade being rolled out to the new-ish LinkedIn Personal Profile format is the ability to visually enhance sections of your profile like your Experience or Summary.

LinkedIn had made it easier to connect items like SlideShare presentations to a specific position with its profile changes in late 2012. However, this recent upgrade is much more visually-appealing and gives your connections the opportunity to interact with the media you’ve uploaded.

LinkedIn Contacts

Your online professional rolodex just got an upgrade with LinkedIn’s new Contacts tool. Integrating your email contacts, address books and calendars with your existing LinkedIn connections helps you to keep all this information in one place. You can even add notes and reminders to each Contact’s listing.

The new LinkedIn Contacts will be gradually rolling out to personal profiles, but you can add your name to the wait list here: http://contacts.linkedin.com. LinkedIn Contacts will also be available as a standalone iPhone app.

LinkedIn’s tagging, Contacts and Professional Portfolio are 3 very useful improvements to the platform. If you had your druthers, what other feature would you like to see added to LinkedIn profiles?
