Microsoft is holding a roundtable meeting this afternoon in the UK to answer questions about their new search engine Bing. The meeting starts at 1900 UK time (I'm calculating that at 2 pm ET). The discussion on Twitter can be tracked here: http://search.twitter.com/search?q=meetbing (no Twitter password necessary). If you are on Twitter, the tag being used is #meetbing. Questions may be addressed to various people including @karenblakeman, @Philbradley and @leggetter to relay to Microsoft during the meeting.
