Only at certain times. In the morning before work, it's Yahoo! Mail, maybe a bit of Facebook or BBC Sport.

During my lunchbreak at work, it's ManUtd.com.

Everything else is done after that. Any other time of day, I just do whatever whenever, usually the following sites take priority lately...

EoFF Forums
EoFF vB4 Test Forums
vBulletin Forums
BBC Sport
Yahoo! Mail
ManUtd.com
