Chaoticsoul: Tags cloud not looking good due to font sizes

Hi,

first of all, thank you for this great theme!!!

My blog is hosted on wordpress.com and I have not tweaked the default CSS. I have added a widget for the tags cloud, but unfortunately it doesn't look good to my eyes: top tags are overlapping with tags from lines above and below.

It's maybe best if you see for yourself stefanoricciardi.net. Anything we can do to fix it?

Thanks,
Stefano
