So it seems whatever you blogs you read at the moment they are full of mentions of Twitter, the current darling of the Web 2.0 world (which sometimes seems to be a small area just south of San Francisco) , with whole sites dedicated to the ‘tweets’ of the twitterati. Now it may just be because I am old, or because I’m an engineer and actually have to work for a living, but I just don’t get this obsession with telling anybody who is sad enough to follow you what you are doing at that precise moment.
