RSS: The Length Wars.

With things finally calming down here, I took the time to look at my RSS feed in Safari (since I have not migrated my NetNewsWire feeds as of yet). I remember asking James this a while ago, but I wanted to pose the question to generate a detailed look at the situation.

Half the sites (inlcuidng Avalonstar) have short RSS feed entries, which I consider to be 250 words or less. The other half are longer RSS feeds, displaying the entries with pictures and all (an example could be Gizmodo or Words for My Enjoyment).

So to make this long story short, what is your preference in regards to RSS feeds and why? When should you use an long RSS feed and when should you use a short one? Time to debate.
