“Linebuzz.com is just about the coolest application for blogging I’ve come across for a while.  Bascially it lets viewers of blogs hilight certain words or phrases and comment specifically on them.  So if, during a paragraph I say Tony’s got no wriggle room - you could hilight ‘wriggle room’ and say, “that’s an idiotic thing to say - it’s one for the plooptionary.  The potential for sabbotage is terrific - I look forward to my posts being rigorously soiled!”
