Rant: Secret Achievements

Is it just me or are secret achievements a stupid idea. The whole idea of achievements is to show off your skill at games but with secret achievements no one can see what you have achieved. Whats even worse is the fact that you can't see what you have to do to achieve them. I think that the only positive aspect of secret achievements is that they encourage players to explore the world more however I find that many visible achievements do the same if not better. I think that in some cases secret achievements are acceptable such as achievements which may ruin the story for the player however generally they are just added to low gamer point achievements. I think overall that secret achievements should either be removed or their use should be improved afterall at the moment they are pointless.
