Micropayments were supposed to be one of the breakthroughs of the Web. Instead of going through a "credit card" process, just click to leave a small payment (< $1.00) for something you like.
With Paypal, Visa and Mastercard dumping Wikileaks, Flattr could make a breakthrough as they've committed to supporting WikiLeaks. Their model is interesting, commit to an amount per month; say $10, and each of your clicks contributes a division of that amount.
On that note, something on the non-relationship between Wikileaks and Anonymous.
