RRW: I like using Twitter. I tolerate Facebook because I have to. And I'm on Google+ because everyone says I should be.
So that has left little time to give love to my profile on LinkedIn, which is, depending on how you look at it, either the biggest niche social network or the smallest of the big, all-encompassing social networks. Some people will tell you that sooner or later, all of our networking, social and professional, will be centrally located on Facebook. Others will insist that you need a LinkedIn profile, if only to protect the eyes of potential employers from falling on photos of you wearing an ugly shirt and a stupid grin at last year's company cookout.
