Dude, seriously! If you truly believed it was futile to come with suggestions here, why would you put so much effort in commenting. You are probably nr. 2 behind Jamboom in comments on this tread.
It's easy to know when Jamboom take a suggestion seriously, and that's when he give an answer that show he is interested. If he don't like it, he won't answer, except if you are rude, than he will give a more or less hidden insult back
Of course it was not all futile, i.e. I was the one suggesting long ago to give users the choice of which shortlink they want to use so the site wouldn't get stuck when the default shortlink went down, jamboom implemented that within a few days and it has worked nicely ever since.
But that holds true only when jamboom doesn't have an idea of his own, bringing an idea to him he never even thought of that sounds nice to him on first view.
Whenever he has an idea himself, theres nothing that can prevent him from doing that, no matter how many users tell him they don't like the idea and this site is full of examples where he utterly failed, i.e. the very first version of CMW he wanted to make, that was terminated due to complete failure before it even launched.
Anyway, I'm not here to change the plans of jamboom, if I can contribute a suggestion that gets implemented, like the one I mentioned above, cool, but primarily I'm here because I like discussing, no matter what result comes out of that.
In fact my favorite topics to discuss are politics and economy, where 99.9% of all discussions never change anyones mind, because opinions are preset and fixed and the discussion is done just for the sake of discussing.
You wouldn't believe in how many forums I'm active, in how many forums I'm one of the top posters, how many posts I write per day for all kind of topics, in fact I've once exceeded the limits of a forum by so much that I ended up literally publishing a book with the content that was just way too much for the economy forum where that topic got started.
