It's a great place for ideas on how to repurpose things you no longer need, or to find recipes, or even for quotes and pictures.
And it has it's share of silly people - for example, the person who built a frame to cover her thermostat. There are several things wrong with that. The first one is that the average thermostat is out of the way and doesn't need to be covered.
The second thing is that by covering it, you're making it harder for it to measure the temperature I. The room, which is its whole reason for existing. Silly, silly people.
