Let's try something. If you like this blog and find it useful, you can use gittip to motivate me. Whenever the weekly tip goes to a value greater than or equal to 3.00 USD, I'll hide the ads in the blog once I notice. If it drops below 3.00, we get ads again. If it never goes anywhere close to 3.00 or even above 0.00, it is all right too, don't worry, don't have much expectations.
