You're right, this is a beginning of an end, as with any other system of this type. But this is a natural evolution so to speak. Once good idea gets into the hands of "bad people"... you know, it's history repeating itself. Don't worry though, something new will come up... Email wasn't the first thing destroyed, there were IRC before it... And I'm sure there were lots of other things before that, like walls in public toilets. I'm pretty sure first writings on them were done by sophisticated and well-educated people, not the typical obscenities you get now...
