The Internet is a haven for self-expression. Anyone can put up whatever they want, as long as they have access to the technology of course. What we have now is a mass of information - some very useful, but mostly... um... poo.
And where there is lots of poo, there be services to help us good people filter the gemstones from the muck. One example is digg.com. It neatly combines poo-filtering with community. Love it!
