Link to an article, 'Trust, but Verify' which should be of interest to all those interested in social networking.

"Security never becomes an issue until it is violated. Our boundaries begin open and undefended, sufficient for integrity, if not defense. But nature thrives on conflict, so every boundary becomes a battlefront in the war for continuing integrity – a war which we all eventually lose. People die. Cities fall. Civilizations collapse. Yet, in each of these failures lies the seed of renewal, and eventual victory. The pressure of natural selection forces an evolution of technique; overrun borders are reborn as more resilient walls, and the eternal battle moves up a notch in intensity." - Hyperpeople
