I read dividend investing stories every single day. A very good compilation of articles on many aspects of incoem investing could typically be found on Seeking Alpha, which is one of the largest blog aggregators on the web.

Another useful website for daily investment ideas is James Altucher's column on Daily Finance. From his bio page "James Altucher is a columnist for DailyFinance. He writes for The Wall Street Journal, was the founder of StockPickr, and formerly wrote and appeared in videos at TheStreet.com. He is the author of numerous investment books, including Trade Like A Hedge Fund and Trade Like Warren Buffett."
The two best dividend blogs ( besides Dividend Growth Investor of course) that I check almost daily include Dividends Value and The Dividend Guy blog. These bloggers are also real investors, which let you observe their decision making process, which has helped them generate several thousand in annual dividend incomes.
For news items, I typically check TickerSpy, which has categorized press releases and other items neatly by ticker symbol.
One of the best value investing blog aggregators is Gurufocus. Besides blog posts related to value investing, the site also includes information about the recent moves of famous vaule investors such as Warren Buffett or Mohnish Pabrai.
