Wikipedia:Articles for deletion/Justin Bieber on Twitter
Obviously, this is a  notable topic because enough reliable sources cover it. In fact, I found more than 100+ news articles having Bieber & Twitter in the title of the news article alone, an oldest being from 26 November 2009http://www.dailystar.co.uk/posts/view/110075/Bieber-and-Swift-became-Twitter-pals/Bieber-and-Swift-became-Twitter-palsBieber-and-Swift-became-Twitter-palsBieber-and-Swift-became-Twitter-palsBieber-and-Swift-became-Twitter-palsBieber-and-Swift-became-Twitter-palsBieber-and-Swift-became-Twitter-palsBieber-and-Swift-became-Twitter-palsBieber-and-Swift-became-Twitter-palsBieber-and-Swift-became-Twitter-pals and a latest being 15 June 2012.http://blogs.ajc.com/the-buzz/2012/06/15/justin-bieber-launches-matt-lauers-twitter-career/ Clearly, that is unusually strong evidence of separate  notability of this subject: Bieber on Twitter: 1. History (@justinbieber), 2. Twitter usage as a communication platform (Technology, marketing and the media), and 3. Reaction (Followers and fans) (I suggest renaming the subsection headings to what I listed). Biber's first uses of Twitter was written about as early as 9 August 2009,http://www.upi.com/Entertainment_News/2009/08/09/Internet-networking-aiding-singer-Bieber/UPI-54371249850178/ and reliable sources have remarked on it since at least 30 July 2009.http://www.courierpress.com/news/2009/jul/30/learn-the-ropes-of-twitter-etiquette/?preventMobileRedirect=1 Beyond being a  notable topic, content consensus at the B-rated Justin Bieber article is that Twitter deserves its own subsection in the Justin Bieber article. Justin Bieber on Twitter is a valid Wikipedia:Summary style article of that Justin_Bieber#Twitter subsection
