I think lj has the advantage of being socially structured; it's easier to keep track of somehow.

One of the wonderful points of the modern world is the fact that nobody seems to realise there is a total disparity between the "global village", the fact that you can contact anyone anywhere pretty much, and the number of things, people, events and situations the human mind can keep track of. The smallness of the world is constantly waved under our noses, but in human terms the world is not small and trying to live as if it is makes no sense. It just stresses you. I gave up on that; I don't follow international or indeed national news in detail, I don't travel more than I need to, I prefer to spend my time on my friends and partners; the things I care about and want to have, not the things I can have. The only real consequence of globalisation for the individual is that you can have anything; and the skill you need to live in a world like that is the ability to distinguish between what you need or want and what is fundamentally irrelevant to your life and only appears attractive because it's there.

This ramble brought to you by my marvellously peculiar brain :)
