Sites with quality, on-topic, inbound links, good internal navigation, with all pages linking back to "/", and with quality content, and a unique title and description per page, as well as proper non-www to www 301 redirects are all fine, with maybe a very few pages filtered (only appearing when &filter=0 is clicked).

Sites with the same title and/or meta-description on multiple pages are suffering with Supplemental Results, or with 90% of their pages being hidden behind &filter=0 on a site: search.

Sites without a 301 redirect from non-www to www, or with all pages linking to /index.html (and with the root page actually indexed as www.domain.com/ instead) are really suffering with dropped pages, multiple supplemental pages, and loss of PR.

Sites with hardly any inbound links, and with poor internal navigation have been culled from the index, with only the pages that have a direct link from another site showing up in the site: search, even with &filter=0 applied.

The sites with problems have been advised as to what they need to fix - but you can only advise people so many times, and be ignored, before you have to walk away.
