"I'm a pretty old fashion cataloger; my images are filed either by event, or if they are not event related, chronologically. I started doing this in the "old" days before cataloging tools. I find I have no issues finding my images using this basic technique."
I have to agree with Manfred. All my stuff is in named folders with titles, i.e. event, place, date, etc...
However, now and again I'll throw in some keywords. I'll just fire up a Metadata template and slap it on a whole load of files.
For doing this I'll use Bridge. It's funny that in these sort of PS vs LR threads, that hardly any mention is made of Bridge.
Lots of things can be done in Bridge. And it comes with PS as a bonus,
