Hi Gordon,
Here's another example of a hotsheet I haven't seen mentioned here before...
It's called
The Best of Journalism, by journalist Conor Friedersdorf.
He finds what in his opinion are the best long-form non-fiction articles.
Each weekly issue (sent by email) primarily consists of the headlines, plus links to those articles. For some of the articles (but not all), he writes a sentence or three introducing the article. The whole thing is less than a page.
He charges just $1.99 per month, but I suspect it would be relatively quick for him to put together (since he probably reads these articles anyway, as it's related to his work).
I don't know for sure, but I suspect he probably has thousands of paying subscribers.
