You could be right about that. We do tend to get a little self-righteous as we get older - we know it all because we have been there and done that, and usually better (in our distorted view of things). I actually didn't mean to be offensive - just wanted to show a little irritation - nothing more. I suppose my main point would be that it is hard to put any faith in anything and use a tool, and thereby usually become dependent on it (to a degree) when the provider could just get tired of it and simply pull the plug at any time. Why provide it in the first place? It just strikes me as being irresponsible and disrespectful of your users. But I do acknowledge that this is just a game, and that the tools are nothing more than handy little gadgets.
As for the cookie thing, I can think of several ways it could have been done without using a cookie and without a username - using local storage perhaps (a number of methods here), or using the ip as an identity for cloud storage, or ... etc.
Anyway, no disrespect intended to the author - just expressing a view. I will now bow out and say no more.
