[sdiy] Silly question about followers

[David G. Dixon]

Here's a silly question, but I just want to make sure I'm correct before
eliminating an inconvenient buffer from a circuit I found on the web:

Is there ever a reason to place a follower after an inverting summer?  The
output impedance from an inverting summer is just as tiny as that from a
follower, so nothing would be gained by re-buffering the output, correct?
