I work in PR, here's my perspective: journalists love Twitter because they can easily share their articles and find interesting news shared by others (much better than Facebook bc you don't depend on a timeline, but rather on public hashtags and trending topics). Because journalists are there, celebrities are there. And because celebrities are there, journalists are there. It's a virtuous cycle. Twitter's also much easier to monitor than Facebook (private pages), so it feeds celebrity egos and the PR/advertising machine at the same time.
