Funny that I saw this - the last thing I did before logging on was to put out a tip for the maid. I tip $5/day unless I'm staying somewhere really fancy, and I always put the money on a little note that says thanks. 

Always. Every day, as there may be different staff. And a handwritten 'Thank You' note.
The price of the hotel stay has nothing to do with the amount of tip I leave. The service and consideration does.
