My Random Quote Generator - Any feedback?

Hi,

Would appreciate any feedback on my random quote generator, any errors, or little pointers to make it better? Some of the quotes don’t seem to tweet correctly on occasion but can’t seem to work out why. I’m also probably going to put a fading effect on the quotes when they generate.

Thanks!

Cool. I love the background. Maybe put the quotes in parenthesis, and format it different then the other text to make it look better. Also you could make the quotes bigger.
