Many into One - basic (4 posts from each of 3 feeds)
Problematic:
Various feeds have vastly different publication rates. Some (eg.: reddit and Digg) may emit a huge number in a 12 hour period while others (Udell and Palast) might not have any on a particular day.
I want to capture the recent from each feed.
So? Given that a full feed breaks FeedBurner's size limit (I take that as diagnostic) that means I have no choice but to throttle quantity.
I'm aiming at a max of 4 from any (with 15 feeds that's more than plenty!) while capturing at least 1 from the most tardy.
Result: Sorting sub-streams and truncating as required.
