Dave’s new idea: “It uses the fact that URLs in a weblog have structure.”
A permalink is a permanent URL link to an item. A place where you can find it after it has aged and slipped off of the front page. A permalink should be archival.
Manila puts the date directly into the permalink like this:
So from the permalink URL you can deduce the publish date of the item, and sort results in reverse chronological order.
Movable Type puts the post id into the permalink like this:
You cannot deduce the publish date from the permalink URL. But you can sort results in reverse chronological order, because the post ids increase with time.
BlogX puts a globally unique identifier (GUID) into the permalink like this:
You cannot deduce the publish date nor sort the results from the GUID. Note also that the BlogX permalinks enshrine the ASP.NET suffix,
.aspx. Cutting edge today perhaps, but five years from now it will be quaint.
