John Gruber at Daring Fireball has earlier had a members only full content feed of this site. The rest of us non-members have had to settle with a limited feed containing headlines and a brief description of each article.
However, starting from yesterday the full content feed is free for all with the only catch that it will be available for exclusive sponsorship on a weekly basis. I think this is going to work because he will attract interesting sponsors and the deal isn’t that intruding on the readers. You can read the details here. So that will be an easy $750 per week for him.
I just wish I had 40,000 subscribers!
