Everything has a good and bad sides, So does Facebook. It has lots of good uses too. I know all those discussions about privacy but It all depends on what you have on it. I have used it from the beginning and it has nothing which worries me (personal data). Compared to Facebook we should more worry about Google since it basically know our whole internet activity process. It even scan our mails in gmails, coz they say its for advertising propose but who knows ?

Like @deanhills said Facebook is great for small local businesses. You can easily get local traffic about find good clients. Its easier than running and website then go through all SEO Stuff.
