I just did it to practice my programming...

Exploratory programming is almost always worth it for its own sake. You can't be creative if you take yourself too seriously - so well done practicing your programming and exploring a new concept at the same time. Ideas and understanding you're gathering right now about this will sit in the back of your head and will make your next project just a touch better.

Again, well done!

This is pretty much a perfect example of a comment so bad, even its creator should have realized it and dropped it before it got anywhere near the reply stage.

Seriously, what idea have you implemented lately?

The only possible way I can see this redeaming itself, is if the author comes out and claims that it is a joke. Meant to be a parody of other karma systems.
