yesterday a service called twittr was launched
basically its like sms but on the internet
posts on twittr are limited to 140 characters which in my mind means its usefullness is going to be pretty limited
with only limited space to say something its not like its going to do anything significant like help overthrow tyrants
and i can't see what people will use it for once the novelty has worn off
mark my words - it will never catch on.
