For those that don't know the #PMOT tag denotes a message for the Project Managers On Twitter.
Of course mst people on the list are bloggers or forum posters and active in the online PM community. But two things stand out for me about this.
Point 1. What the hell are you getting done at work if you are posting upward of 200 tweets in a day?
Point 2: Oh okay, you are using a whole bunch of automated processes to push out tweets, so you aren't in fact spending your whole working day pasting in URLs of interesting content. So you are spamming.
For me Twitter's eventual failure is apparent in these two points.
