I didn't read the original notice of GBO signing on to the the blackout, and earlier today when I clicked on the site and got the blackout page, I was surprised and reloaded it, thinking my computer had somehow gone back to the Wikipedia site I was on earlier.
Nope, it was still there, and then I noticed the GBO note at the top of the page. I was actually pleased to see that you had chosen to make the protest. I did winge a bit that I couldn't get on my favorite site (instant gratification foiled) but that quickly replaced by my pleasure, and pride, to be associated with GBO for taking the stand.
Kudos to you Matt and Bill. One more reason for me to treasure GBO!
