Main thing is to publish. Blog, tweet, write, photograph, tweet, video, code, play around with data - or a combination of all of the above. a) it will keep your journalistic ‘muscle’ in practice. b) if you’re any good, you’ll get noticed. And bear in mind you can do these things at other places than conventional news organisations. Many businesses, NGOs, arts organisations, public bodies, universities, etc are now publishers of extremely high quality stuff. Good places to practise your craft before moving on.
