The disk on which my home directory resides filled while NetNewsWire (v. 2.1) was running. Later, after freeing some space and restarting NNW, I found that some of my feeds are missing data.

It's understandable that new items on a feed would be lost, since there was no place to write them. That existing data was lost, though, is *not* understandable. It looks like this stuff is stored as XML with one file per feed. Why would the old version of a file be deleted before verifying that a new version had been successfully written? Why not store feed data in an SQLite database or something similar so that updates can be performed atomically?

Brent is in the process of re-engineering the data store for NNW 3.0 so this won't happen in the future.
