It would have been nicer if even more people had gone out for it but I guess that’s just one of the problems with organizing such a thing on short notice. Given the time from announcement to protest, I think it went pretty well. It seems like there were definitely enough people to make it work.
Of course the Defective By Design folks let you sign up now so you won’t miss the next one if its in your town. If DRM is going to be successfully opposed this decade, it will be through education and activism in the next months and year. I think that it is very important that people get involved.
