I think you should build your LinkedIn account and profile. If built well, you don't need to send résumés or portfolio to potential clients or employers. You can just send them there.
However, like every social media platform, your experience with it depends on your friends, followers or connections on it and your interaction. Communicate, share, comment, and learn. That's how you build.
My present boss only asked for my LinkedIn profile and checked it out.
While it is being abused or misused by some, it is a professional social networking platform. If used right with the right connections, it is highly rewarding.
Cheers.
