I hope you're not upset, I give you credit by linking to yours, right?

I just want to try the voting-in-comments-idea ... I was already working on it when I saw your post

Thank you for letting me know you were doing it. But I'm not ok with it. I put a lot of work into that post.

I went and found the content I included in it. It didn't fly out of somebody elses work and slap me in the face. I spent time and effort seeking it out.

I haven't flagged you. But I would warn you to be more careful, as there are lots of people who would if you had done this to them.
