"Blog entries should be organized by popularity, not time. Or ideally, you can
pick either one. Why the hell don't blogs do that?"
Voting on good or bad articles for a blog? This is a good idea.
"For instance, I want inline comments. Putting everyone's comments at the
end is pretty lame. Even worse, most blog packages these days don't even
seem to have Slashdot-style threaded commenting. Instead, the comments
are ordered chronologically, just like the entries."
Comments along the side, remarking on the story as it goes? This is a good idea.
"And I want versions. I want to make changes to my entries sometimes --
heck, frequently. But that's culturally weird, and feels dishonest to me,
because I've sort-of permanently overwritten the old version"
Diffs? This is a good idea.
"All that revision-history stuff complicates the commenting, of course; each
comment has to keep metadata about which blog revision it was talking
about. It's even more complicated if you have versioned comments, so
users can go back and fix their typos or change their minds."
This is a good extension of the previous idea.
"When I go into Firefox, I want to be able to override every single
configuration option on a per-page basis, or even better, with url pattern-
matching rules. Doesn't that seem just patently obvious?"
... uhm. Well 4 in a row aint bad.
