It seems that one thing common among micro-bloggers is that they have a Now page on their site for the purpose of sharing what one is currently working on.

I followed that trend but have not been in the practice of updating it as there is simply too much friction to do so. Instead, I find having a Now page in my Federated Wiki to be much more useful and dynamic. If you want to edit a page frequently, you need the easiest way to do so.
