Just in case you want to show your appreciation for my blog posts, my open source tools and libraries and my contributions to other tools and libraries, now you can: I have created a profile at Flattr and embedded a button in my blog.
For now, this is mostly a test to see whether it actually works as described, but feel free to “flattr” me anyway.
Note: I deleted that account today, 2017-10-21 due to flattr changing their terms and condtions.
