Lets Talk Aggregator

[Useless]

From what I understand, the ever-decreasing speed of an aggregator as it ages is due to the fact that many of them (aggregation scripts) go through and scan what you have stored in your database from feed A and compare it that to feed A's present state. That's a lot of work, especially when you have that many feeds being handled and a now monstrous database. A more efficient aggregator would look at the post dates and add only what's new from a feed, instead of checking to see if old posts have been updated/edited. If they didn't get it right the first time, fuck 'em.
