I don’t know if I had mentioned this before but I was a fan of the original constraint that Twitter had when it was introduced to the public. Each tweet could not be more than 140 characters and there was no retweet function. Now tweets can read like blog posts. This totally messes up the flow of Twitter. You might as well blog on your own site or get a Tumblr or WordPress account.
With that rant out of the day you should read this brilliant breakdown of the Wall Streer versus Main Street dynamic when it comes the methodology behind each profit measuring.
