>I am not against "like" button but I doubt that it will work here without user registering or everyone will be able to click it as many times as they desire and it will be pretty hard to prevent people from pushing it 20 times in a row.

Certainly we wouldn't want registration, but we can just think of the "like" button as being a substitute for posting a reply that says "I like this". There's nothing stopping people from posting such a reply 20 times in a row right now. The like button would just let them do it without messing up the thread, so it would be a purely positive way to make your satisfaction known.
