I always find it very interesting when we start talking about fitting more into less when it comes to content and knowledge. Conversations constrained to 140 character at a time.. I personally don't believe it works. I'd rather see the content of a twitter post as a title that links to a more in depth thought. I do believe that there will be people that won't be able to concentrate for more than the 96 seconds mentioned in the post, but I also believe the actual knowledge sharing will continue to take a little more of our time. Pictures and video will help shorten the time spent, maybe, but not by much. Will we end up with the haves and haves not of concentration and focus?
