I fully agree.<p>Facebook will eventually be supplanted by 'the next facebook', in whatever form it will come.<p>Lots of people disagree with this, but I feel that the root of their demise is in the seed of their origin. You can go a long way on a bad mentality but eventually it will catch up with you.<p>That said I don't think they'll ever die completely, just very slowly wither away while one or more other networks will take its place.<p>I believe facebook does not partake in open social precisely because they are afraid of that.<p>A really good social site has no fears of losing its users and so does not need to lock them in.
