Having duplicate meta description tags isn't necessarily hurting a site--but it's not helping.
I'm a big proponent of having a very "clean" site, and fixing everything that can be fixed:
- links to pages that redirect to other pages
- links to pages that have 404 errors
- unique title tag on every page of the site
- unique image alt tag attributes on every image
- unique meta description tag on every page of the site
I put having a unique meta description tag on every page of the site just as important than having a unique title tag and properly adding an image alt attribute on all images.
