It's incredible the amount of messages crossing the network. Words, words, and words in the largest community of people that the world has ever seen. Forums, blogs, chats and declarations that occur in real time or half real time and then die, or later are taken up, as sounds that go with the wind but that someone is able to recover.
Have you ever considered that they all are like echoes of conversations that will remain, perhaps, many years longer than their authors? I do not want to sound tragic, but have you imagined how many existing posts in the network may belong to people who have already left us?
No doubt, the post we do in weblogs will last more than the sound of a conversation in a village street, and if that makes us happy, we can pretend that this is our timeless legacy to posterity. But be careful, it is only an illusion of eternity. Computers are renewed, bits of information are lost here and there, the networks may suffer radical technological change in the future, and even a huge solar storm could wipe out the memory banks.
Whether we like it or not, a server does not have the durability of a stone wall carved in hieroglyphics. However, if the bloggers legacy must serve future historians and anthropologists, we should wonder about the validity of what we write with an aim to remain on the network. Perhaps it is better that it is all lost over time, isn’t it?
