Absolutely love this!
Chris McLeod has created a feed-only blog that, as the name suggests, you can only read in a feed reader. No permalinks, no archives, just an Atom feed.
I've long been intrigued by the idea of an ephemeral blog and this, by its very nature, is likely to be one. As Chris says:
By its nature, entries might also be somewhat ephemeral. If you subscribe after, say, Entry #100, then I cannot be sure a feed reader will import right the way back to the beginning.
Not only that, but he has ultimate control by deciding how many posts appear in the feed.
It will be a fun experiment to watch.
