Occasionally I'll go on you tube but the others no chance, I've seen too many people get into trouble using facebook talking to everyone else's missus and the like behind other peoples backs and twitter I just do not get but then again I'm 50 so it isn't really for the likes of me anyway.
I use youtube for music and sports videos. Facebook for keeping up with family as we are spread far and wide across the country. Twitter is the biggest waste of time going as I really don't need to know when people eat their breakfast, feel ill or go out.
heavy FB and Twitter user.. Youtube is for consumption only - dont think anyone wants to see me. Needless to say always be aware of what you share - esp on FB. Enjoy this video. http://youtu.be/F7pYHN9iC9I
Facebook for keeping in touch with family and friends...and I mean friends rather than any tom dick or harry I once met in the local supermarket!
Twitter - occasionally but not regularly. Follow a few sports people but that's it and never tweet apart from when Srixon had a competition on and I won a tour bag
YouTube - for videos when recommended to view on here.
I like Youtube, it has just about every bit of music on it and some good golf stuff. I use 'SKYPE' quite a lot, I keep in touch with family and friends all over the world, especially my Son and two little Grandsons in Chicago.
Use them all, YouTube for music and videos that will be of interest. Twitter I find good for instant sports updates from the likes of the been an sky, much quicker than logging into their websites with my phone as twitter updates as scores do. Facebook well family is spread far and wide across the continent so quick, easy and free is the best method. Though I do find those people that update about hourly about their life story irritating
Apparently, employers can check up on job applicants by searching through what they've written and uploaded on youtwitface so be careful what your write if you're thinking of moving jobs
