I barely use it. Realised I was spending far too much time doing exactly nothing of consequence on there. Now I use it as a chat client for a couple of people who don't use other 'old school' clients.
And as a lazy way to half-heartedly keep in touch with people I don't see that often. (eg mates back home since I moved to Australia). Email and Skype, etc do a better job on the whole though.
I think some people have a fairly serious problem with the likes of Facebook. The need for recognition of everything in their lives, it's as if they don't know how to experience moments in their lives for themselves. They have to share it online to make it real. People posting real time updates from hospital as they stand by a family member taking their last breath, etc. quite disturbing.
Facebook has so many uses, I don't see how you can't use it these days. Keeping in contact with family and friends, sharing family photos, keeping up to date with companies/products as a lot now share info through facebook and communicate.
Pretty sad state of affairs if you can't imagine life without Facebook. :| (As I said, I do use it to a degree myself).
People had family and friends before Facebook, now there are mobile phones, free VOIP and video streaming services, email... definitely no need for Facebook to keep in touch easily.
Sharing family photos, yea FB makes it easy, but there are of course dozens of other ways to do it, most give you more definite control over where they get stored too. (My parents have a server at home in the UK, easy for anyone to log in from anywhere in the world, and Zuckerberg doesn't get to keep your photos).
Keeping up with companies - I get enough spam through other channels without volunteering for it on FB.
what I like is when people put their facebook profiles on their CVs
People put their Facebook profiles on their CVs?! What do they hope to gain from that?
