The Huffington Post announces that it is hiring a political editor and will start reporting with all that brings: deadlines, expense accounts, and salaries. It’s the next step for HuffPo and the blogosphere, to add more original reporting as it becomes worthwhile to do so. And it’s the next step for more and more institutional journalists to venture into the future. The HuffPo editor, Melinda Henneberger, comes out of Newsweek and The New York Times. Note again Washington Post political editor John Harris and a colleague leaving for an online effort. All three quickly say that there’s nothing wrong with print — nothing, clearly, except that they don’t see a bright a future there. Note, too, that it will soon be more difficult to tell the difference between old and new, as blogs and reporting and reporters blog. It’s all news.
