If you go to Pajamas Media (or Instapundit or Powerline or the right bit of CNN) you'll see that there are some enormous (as in tens of thousands or participants) protesting Obamacare and other related issues in Washington DC today with many more apparently in protests elsewhere.

But if you look at screencaps of the CNN/US webpage or the Yahoo Reuters headline list there's not a single story about it.

On the other hand there is this amusing set of "Top News Photos on the bottom of the Yahoo Reuters page:
Surely if the photos are news worthy someone ought to write about what is happening?
