job application asks for twitter username, should I give it?

[kiki_chiqui]

On a media job application form it's asking me if I'm on twitter- If you tick yes, you have to give you're twitter username.
I am on twitter, but I'm unsure about giving it out for a job application. It's a personal account, but open to public.. it's not TOO embarrassing. The job is in media, so it would be good to show I can use twitter and social media.... just really unsure. Anyone had this problem before?
yes it's a required field
