calculoso is correct in both respects. The thread didn't meet the level of "quality" that we'd like to see for threads and discussion. He's also right in that those kinds of questions can be directed to the Moderator account, though I'll answer this here as it might be helpful to others.
The thread wasn't locked because of the idea itself, but the presentation, lack of support (i.e. you can't start a thread like that and not stick around to support your idea, otherwise it's like a drive-by shooting), and how the thread progressed made it a lame duck thread; there was little meaningful discussion taking place in it so it was locked.
You'll also note that the moderator locked the thread because it was lame, not because the original idea was or wasn't lame.
It's got nothing to do with ego, we usually discuss things like thread locking as a moderation team to make sure we agree, so ego isn't a part of it.
Hope that answers your question, if you have further concerns you can PM the Moderator account.
EDIT: Oops, didn't see KG had posted, as you can see he can say what I can but in far fewer words
