I recently set up a LinkedIn profile after avoiding them for many years, and was horrified to discover that there's now a "Facebook wall" feature, replete with all the horrible political conversations that made me abandon Facebook. It's totally in-your-face, too; it's the default home page and the default Android app page. I don't want to see what people I've connected on LinkedIn have to say about, well, anything. I only maintain social connections there to help me network with potential employers. I'm deleting my LinkedIn profile as soon as I connect with my next employer.
