The blog is good. Well done. I clearly know its not been easy…However check up the links for Facebook and Twitter in your blog. It appears you did not use the right address, because when one clicks on it it shows a sign up page for the sites and not your own.
Visit other peoples blogs as well and make comments. It will help you evaluate and better yours in some way.
Otherwise good luck.

I love your collection of physics resources on the Diigo. I will be visiting more often.
