Off topic: I saw your comment history and in the previous submissions you added a bunch of comments. It's not the usual custom here and you will probably get downvotes for it.
If you have something interesting to say, add all of it in a single comment, unless other users add questions and you have to reply with more information.
Also, you can edit your comments for some time (1 hour?) in case you forget something or discover a mistake.
How flattr works: When you're registered to flattr, you add money to your account and set a monthly budget. During the month you flattr creators by clicking the Flattr-button next to their content. At the end of the month, your monthly budget is divided between all the things you flattered and sent to the creators.
