A lot of websites dump the entire feed — that’s nice. Ideally for bandwidth efficiency, combine multiple delivery strategies.
A partial content feed (Atom preferred) limited to the last
3/5/10posts for quick queries.
A full content feed of a similar limit for fresh content.
A hidden/unlisted feed for dumping all content (mirror).
Alternatively, just implement atom’s collection partial lists for feed pagination. If your post bandwidth (size/frequency) is low, then pretend you didn’t see this — be lazy and optimize later.
