Why not creating something useful...? Rated 2 out of 5 stars
To be true: Advertisements need to be clicked to earn money with them. So it is anything but helpful to show ads for a site, but annoying to the person who still isn't interested in being disturbed by blinking (or even worse: Flash) Banners.
I have no problem with discrete, decent advertisement and - moreover - if the advertisement is correctly placed (that means it is related to a website's content!), I often click it, since I also often search for new sites.
But advertisement because of 'sympathy' to a website - independent of the manner of advertising - for me a categorical NO GO!
So this AddOn, sorry, is in my eyes simply a waste of time - for the user as well as for the programmer - once again sorry.
Use your time to create USEFUL software - useful for everybody.
