What's so bad about it? Maybe not all of your posts in this topic included new information, but at least you expressed your thoughts. Now you're able to summarize and review the ideas you've come up with, and try to get them in the
wishlist (I've got no idea how and by whom function ideas and wishes are submitted and managed, but at least it shows what the development team is working on, supposing this list is correct and up to date)
And about the trolling: I don't think it's as serious as you might expect it to be, at least not in the case you are referring to. In my opinion it would be a shame if you stop posting good ideas just because someone else thinks you shouldn't do that all the time.
