I like the concept of micro payments, but I am worried about the notion of a single large party providing this service. Can you imagine the worth of all those user profiles correlating topics, interests, articles, and websites?
Payment would have to be anonymous for this to work.
Monetization of content is a business opportunity waiting to happen. Something like a network where you put, I dunno $10 per month and every article you read is charged for $0.10, as an example. Or unlimited during the month for $1
If news sites can allow us to Tweet or Fb an article it might be possible to 'coin' an article as well in a seamless manner
