Ads on the website

The is an experiment to add ads to the website. We have about 10.000 unique visitors per month, why shouldn't we use that for something good?

The idea: Add non-intrusive textual ads and invest the revenue into something like https://www.bountysource.com/
With this money we can tackle the hard issues that nobody wants to resolve and hang around forever. Depending on how much the ads make, we can also add a bounty to the normal issues. This means that you, the developers can make some side-money working on Mahapps.Metro

Note that this is just an idea, we don't have to do this if nobody wants ads on the website.

Here is a screenshot on how the ads might look like:
