Fundamental unit of weblogging

· Weblog Concepts

Does filtering or re-sorting the contents of a blog site make the sequence of entries any less a weblog if the reverse-chron order isn’t maintained?
Anil Dash notes (and I believe there’s a consensus for this) that entries, or posts, are the fundamental weblog particle. Less clear, he says, is the question of the reverse-chronological order of posts.
Is the most-recent-post-first structure an implicit promise or signal that the weblogger intends to keep the site current?
Peterme has an interesting observation about categories too, noting that not all personal conversation can or should be pigeonholed.
