Brian Stelter: Today I'm publishing my last post on TVNewser, 15,470 entries and 1,297 days after launching CableNewser. It started as an anonymous project by a news consumer, but before long, the site was being read by the same people I was writing about. Shortly after The New York Times revealed my 18-year-old identity, mediabistro.com turned me into TVNewser — providing generous support and enabling the blog to attract more than a million page views per month.
