I already threw some STEEM away for PAL. Not much. I just wanted to learn how to use steem-engine. Then I wanted to be able to pass some PAL around on posts. I upvoted yours as a test case and have no idea if $30 worth even helped you.

I have no idea either but, it is appreciated :)
I think at the very least all these things give the place more things to experiment with and see what people are interested in (besides coins).
