This just in ... a smallish but interesting acquisition by NBCU, the new owner of Rmail.  Randy Charles Morin, founder of the RSS email start-up, announced the sale late night Wednesday on the company blog: “What does that mean to Rmail users? It means a lot of new stuff is coming, as we finally have the team to make this joyride a rollercoaster.” The most recent numbers on the site boast of 50,000 plus users, 100,000 subscriptions and over 50,000 emails per day.
