Slashdot provides more musings on micropayments, including Bitpass, the new system used by Scott McCloud for The Right Number webcomic.
UPDATE Almost missed this NY Times article also on micropayments that also mentions the McCloudster. One thing the article mentions that I think has not been previously reported on is that McCloud owns a small part of Bitpass:
When the BitPass founders showed him their plan, he said he liked it and agreed to use BitPass to sell comics on his Web site (www.scottmccloud.com) and to serve as an adviser. He now also owns a small, undisclosed stake in the company.
