Impressive, I too was gonna do 1 article a day, but while I am not a perfectionist, I hate working with low-end devices, which is what my PC currently is. Still waiting on my new one to get shipped out. Also, I have the discipline to commit 8 hours daily at my workstation, but I lack the consistency to pen down articles daily, even though I have dozens of things floating in my head. Perhaps it is time.
Good luck with your HP, may the 500th be with you ^_
