Bay seniors in no mood to deal with the traffic, parking and high prices of local entertainment need only tap into their computers for some high-minded stimulation. The Moth is a storytelling site on-line and on the radio (there are also local live performances) that includes both amateurs and luminaries like Walter Mosley and the late Christopher Hitchens and George Plimpton. For everyone who can’t score the $7500 tickets to TED – the Monterey conference of global innovation – you can view most of their cutting edge 18-minute talks on your computer. Both sites are free. The New Yorker and the New York TImes similarly have videos and podcasts on timely subjects by celebrated commentators. Subscription required. Any readers have any other favorites to suggest?
