Re: Atom, threading, etc.

having per-entry comment feeds isn’t very interesting right now because the subscription process is not well automated

Another problem is that it scales very poorly if a reader wants to stay informed of all comments on a weblog. You don’t know when someone will post a comment on a long-silent entry, so you would usually need to poll them all.
