BBQpitboys.com is a great place to learn about recipes for your grilling needs. Namely, charcoal grilling and BBQ.
The layout of the site is a rather messy affair, but amongst the textual information, I find the true source of delicious knowledge existing in their youtube videos. That gruff Texan-accented narration just makes me quiver with delight as they lay it out flat how a pit master gets the job done. They have recipes for a multitude of BBQ related items -- be it beef, poultry, or pork. There's even some videos on grilling tips and tricks.
If you're into grilling or BBQ, or just have a passing interest and want to liven up your culinary skills, I would definitely scope them out.
