I had left a comment on the question Does this site want to succeed? but it got deleted. Why?
It was just a routine cleanup of a misplaced comment. The comment was essentially just saying "+1" followed by a list of some meta posts you had also written. There isn't much more to it than that.
If someone has an answer or would otherwise like to respond to something being discussed, they should post it posted below as an answer. I can appreciate that sometimes folks don't really have an "answer" but want to jump into the conversation nonetheless. But comments were not designed to be the mini chat room or discussion section of Stack Exchange, so if a comment is not seeking clarification or otherwise suggesting improvements to the post, they are subject to being removed. It's just the way we keep the right tools being used for the right job.
