It might sometimes seem a hassle to keep on top of your social media. Posts and tweets can feel as if you are casting seeds into the wind - but occasionally those seeds bear fruit and make it all worth while. I have just secured a job through twitter. Somebody saw my show reel and biography and thought I was right person for them and it turned out I was. So, keep all your information up-to-date, keep putting out information and retweet and share posts - it does work. It pays to be sociable.
