I enjoy screencasts, but I really can't understand what Mr. Macedo is saying in his screencast. I enjoyed the RoR screencasts because I didn't really need to watch them, I could just listen and work in another window. This would be a great idea if Mr. Macedo spoke in better English, it's not something he can control but it's a big deal from a final product viewpoint.
Mr. Macedo speaks perfectly comprehensible English. I understood every single word he uttered. Your comment is unnecessary and hurtful. What would be a "great idea" is if you added value somewhere instead of putting people down.
Mr. Macedo keep up the great job!
