I loved LinkedIn, was one of the earlier users, and have found it to be an indispensable tool for professional connection and networking. They’ve stayed on top of keeping their platform on track by now allowing you to connect with people you don’t actually know (on some level) via their email address. The recommendations piece is especially valuable as it serves as a virtual list of solid references along with your virtual career portfolio.
However….I’m disappointed with their new “recommend” feature. I’m getting recommendations for skills I’ve listed, and they’re from people who have no way of knowing whether or not I have those skills. The first time I went to the site to reciprocate, I discovered that you can actually click on four at a time and just randomly recommend anyone on your list for anything. I hope they remove this feature.
