why down vote. Should i take my congratulations back.

You were most likely downvoted because people don't want threads filling up with a bunch of "congrats!" type comments, which are admittedly friendly but don't really add anything to the conversation.

Even though one or two might not seem like too many, "none" is a simpler heuristic than "how many are there? Ok, we have enough, downvote any new ones..."

Thanks much!
