Here's a small idea I've not yet had the chance to try out on a large scale: Time-based pagination in lieu of page-number-based pagination for personal content - ie. blogs, bookmarks, status updates, etc. (You know, User Generated Content except I dislike the term.)
Page numbers change over time, while time-based URLs are stable. Most people don't generate an unreasonable amount of stuff in a day, so a page-per-day might not be so bad. But, if there's too much stuff, degenerate to a page-per-12-hours or whatnot.
Delicious used to have something like this in the web UI, back in the mists of 2003 or so, but Joshua got rid of it after a few design iterations. The Delicious API is still somewhat based on it, which causes some confusion—but I tend to like it, thus this post.
You mean, like the date-based archives that Movable Type has had for ages?
Yeah, I like those.
I've had the same idea for Upcoming, for obvious reasons... our SRP pagination would then be permalinks.
Actually, yeah, we built the default pagination for archives in MT4 to be category-by-month, for exactly this reason. I regularly see "?page=2" in URLs and it just seems like such an obvious, avoidable mistake for so many to have embraced. SEO aside, permalinks that are destined to expire over time seem pretty reader-hostile, too.
