Feed times
It's amazing what a feed aggregator such as Planet Planet needs to put up with. Apparently some posts don't have timing information with them, so planet needs to invent those times (which it does by the time a post appeared in its cache).
Since, however, my planet is still rather young, that meant I had three people flooding it already. Ugh. So I just opened the foo,times file in an editor and set the times for the posts of those people to something a bit older, based on what the HTML on their blog said the time of the post was. Which begs the question: why don't people just publish the time in their RSS feed if they do publish it in the HTML anyway? Oh well.
I've already added some extra feeds based on the suggestions Kris sent me; and more are, of course, always welcome!
