I want to use tagging on MacOSX, mostly for pictures, but may extend it to other files too. Caveat: it must be compatible with Leopard, because most of my files are on an old (pre-intel) iMac.
I have browsed, among the others: - http://www.gravityapps.com/tags/index.html - http://onflapp.wordpress.com/tagoman/ - http://c-command.com/eaglefiler/ - http://hasseg.org/tagger/ - http://www.ironicsoftware.com/tagit/
and I am currently testing tagit - mostly because it's free, and because I suppose that I am satisfied with the results I can move to some other (non-free) product by IronicSoftware.
Have anyone tried this already? Using what? Results? Caveats?
I also noticed that apparently tags placed by tagit do work with Spotlight, but are not recognized by NiftyBox (unless I need to do something special that I somehow missed in my brief test).
Is there any chance of interoperability among tagging products?
