Superfeedr, a service that transforms a wide variety of feeds into normalized XMPP or Pubsubhubbub format, announced a seed round of funding from some very high-profile backers this morning. Betaworks, backers of Twitter, Bit.ly, Tweetdeck, Twitterfeed, Tumblr and more, and Mark Cuban, have invested in Superfeedr's parent company Notifixious.

Superfeedr offers services to both publishers and subscribers. Current marque users include SixApart, Adobe, Twitterfeed and Posterous. Notifixious founder Julien Genestoux first met Betaworks CEO John Borthwick at our event last month, the ReadWrite Real-Time Web Summit.

Four years ago, an eternity in internet time, Dallas Mavericks owner and controversial web thought leader Mark Cuban allegedly used inside information to dump all his stock in meta search engine Mamma.com hours before the company announced a round of fund raising that caused the value of stock in the company to drop dramatically. That's what the Securities and Exchange Commission says, at least, according to a short but high profile report this morning by the Wall St. Journal. Cuban owned a 6.3% stake in
the company.
