After processing my RAW files in Lightroom, I often export JPGs to give to people or to post online. I create these files in a directory structure under an \Export top level directory. I'm trying to decide whether it is good practice to add these files to my Lightroom catalog (or perhaps create a separate catalog just for exported files).
I'm kinda hesitant to add them to my main catalog, as I don't know that I need to ever make changes to them, and I can always recreate them from the original (plus non-destructive mods stored in the Catalog for the RAW files).
On the other hand, it might be handy to have all your output files in a Catalog so they can be searched/sorted quickly and easily.
(A related question might be: should I even keep exported files once they've been delivered/sent/posted?)
I realize there are arguments to be made, and there probably isn't a "correct" answer, so this may be too subjective, but I think the arguments themselves are valid and useful to others. The "correct" answer may be different for each person.
