Oh no! Someone's trying to turn the Facebook party into a work party! Amid all the fun and games, it seems there is real professional networking value to be found on Facebook. AskBINC, a recruiter/technology blog, becomes the official wet blanket with this post: 20 Facebook Applications to Assist in Your Job Search.
A quick skim reveals that all the major job boards and aggregators will let you put a jobs feed on your page--helpful, I guess, if you use Facebook like a home page. I'll have to study all of these further; for now, the idea of adding a link to my LinkedIn profile, which I've worked much harder on, sounds like the biggest winner of the bunch.
Lest you pooh-pooh the idea of the professional value of networking on Facebook, I have to brag that yesterday I was able to connect a friend in need of legal services with a relative who is a lawyer--all because of Facebook. There is wheat among the chaff!
Thanks to @lindseypollak for her timely tweet on the subject just minutes ago!
