As with many open-source projects, there's really no one to ask. But
as one of the developers, I'm happy with it. You can see my tour page
at http://www.parc.xerox.com/istl/members/janssen/pubs/plucker-tour/
if you need more reasons why folks should use Plucker.
As far as I can tell, Plucker is really one of only two decent
open-format ebook readers around, for any computing platform. (I
don't really count the Doc readers; they're simply juiced-up text
viewers.) The other is Adobe Acrobat Reader, and that's not
open-source, and has other problems with its page-image model.
