I liked reading the comments about using an open string to allow a position change in a challenging bass line (or reading) and the comments about the importance of muting. Both reminded me of Jaco examples. In Teen Town, the third measure (after the intro) uses a open A to allow a position change. That's tough line to play at tempo, and I can't imagine trying to "fret" that A. Barbary Coast is an example of muting. Some of the ghost notes are natural harmonics or muted open strings. Towards the end of the song, Jaco mutes the open D on the "a" of one (1e&a). Because the root is C# (on the 1e&), the muting of D is critical. So the one beat goes C#, C#, C# (up an octave), and then down to the muted open D.
All that said, I usually avoid open D and especially open G for all the reasons expressed above.
