I agree that the original post is lousy -- it's not well written or proofread. We should demand better for upvotes. However, if it had been a better looking post, I would certainly have upvoted it because @joelinux's question is a very good one. Many people coming here and seeing Steemit for the first time are asking something similar in their own minds.
Even if you are upvoting Dan, I believe the original poster shares in that; even a careless post can trigger a robust conversation!
Huh, still very confused over here but at least I know that I enjoy using it, even if I have no idea how it works.
