It seems like a great idea to generate modest revenue for content creators of all kind. So I gave it a try. My blog is usually not very high traffic, but there is a steady stream of 6-7k visitors to my old articles. Those articles generate a time on page between 6-10 minutes each. I like to think that people stay and enjoy the read. So I made myself an account and installed the official flattr plugin for WordPress.
10’000 unique visitors to my blog later, I received no single flattr.
By no means does my experiment imply any significant validity for the general public, but I see no reason to keep the advertising buttons on my blog, either.
