2. The law of saturation: If a user keeps receiving merits without giving out, there should be a limit to which he/she will no longer recieve merits unless he begins to give out. If this law is applied by Theymos, the talk of merit hoarding will be a past.
I don't believe theymos will make any significant changes to the merit system. Limiting someone on how much they can receive would be a drastic measure in my opinion. Instead, the community can do their part just like they do with scammers or account sellers. There are no rules that forces users to award posts with merits, but there are also no rules to selling Bitcointalk accounts or scamming someone and we know what happens with those people and their accounts if they are discovered. The sanction for those who don't send sMerits could be simple. You aren't going to get any because it's a waste of sMerits giving it to you when all you do is keep them for yourself.
That's just another reason not to award them with more if you ask me.
