What do you know about compact fluorescent (CFL) bulbs?

A good number of community members that the be cool team encounters tell us that they're already using CFLs. It is an obvious energy saving choice and many people have caught on.

We may know they're good to use, but lots of us still have questions about CFLs. Where can we throw them away? Are they safe? Do they malfunction in damp places? When should you turn them off for maximum efficiency?

We've got CFL information on the ImCool.info site under the "Change your bulbs" action, but we're curious to know your thoughts on the subject. Have you come across good resources that you'd like to share to help the cool crowd become more informed about CFLs?

Here's one story to get us started - the EERE's answer to when you should turn off your lights.
