I've stumbled upon flattr :-)
Flattr is a social micropayment platform that lets you show love for the things you like.
As I've always looked for a service like this to show other people my respect and want to give them something back, I think this might be the right platform to do this. I've added a button to each of my blogposts and if you like what you read, you can press this button.
Of course, you need to be a user of this service, so please register for a beta invite or ask me at harryd71 at users dot sourceforge dot net or send me a direct message on twitter.
Many thanks for your support!
P.S.: Nico showed on this blogpost how to add a flattr button to blogger. Many thanks, Nico (of course, I've flattr'd you :-) )
