hi darcy,
I didn't mean that the more was redundant in general, just that it is when you use the_excerpt - and only in the sense of shortening your posts because the_excerpt shortens them automatically.
I actually use the more tag a lot and you're right! It's a great tool for showing the reader that there's more to your posts than just what they see on the index, search, category, or archive pages.
ProSense is basically just using the_excerpt to cut down on "duplicate content" and keep those search, category and archive pages a bit quicker to navigate.
If you'd like to add the "Read more" link to those templates you can do it pretty easily - you would just need to edit a couple of your template pages. If you're interested in doing this, and no one beats me to the punch, I'll gladly post some code later.
I'm not at my dev machine right now so I'd hate to do it off the top of my head and be wrong.
Sorry for any confusion.
