Betaworks, the NYC-based tech investor and social media incubator that has positioned itself at the center of the ‘real-time web,’ has raised $20 million in a round led by RRE Ventures and Intel (NSDQ: INTC) Capital. Other new investors include AOL (NYSE: AOL) Ventures, the New York Times (NYSE: NYT), Softbank Japan and Softbank NY, DFJ Growth, and Lerer Media Ventures, the company tells us.

The sites Betaworks has incubated or invested in are a who’s who of the hottest social media startups around right now: bit.ly, Twitterfeed, Superfeedr, Chartbeat, DailyBooth, Hot Potato, Outside.in—to name a few. Betaworks also owns a stake in Twitter via its sale of Summize to the company in July 2008.
