BRAIN WAVES: neurons, bits & genes:
Only money can eradicate spam. The Internet is a globally distributed ecosystem complete with evolving organism/organizations that continuously adapt to change. The current spam epidemic is proof. Moreover, no legislative or technical solution (i.e. filters) will be able to stop it. Why? Because spam is fundamentally an economic problem.
Nice item with a great idea from Zack Lynch on the Corante website – which filters news – is a weblog? With various subsections including the Many-to-Many which is good on groupware.
