Hey, I am the author of the above tiny rant and what prompted me to write is exactly the case you are describing. I am working on monetization features for WordPress.com and Tumblr users. Micropayments are one of the cases we are considering and this post came out of our internal discussions. There is a TON of context I am omitting in that post. In particular, I think that niche sites can run micropayments because early adopters WILL use them. But the economics of it means that you need to cross the chasm to the early majority in order to break even. But the early majority will be more conscious about these tiny amounts of cost. Alternatively, I can be totally wrong, but this whole thread is an awesome discussion :)
