how did you deal with the /article-name vs. /article-name-1 potential Duplicate Content issue

In this case we don't resolve article-name-1 - it is 404. The URLs are created manually rather than automatically generated, so it's not a complex set-up. For automated URLs I suppose a 301 could be instituted to strip the "-1" from any requested URL.

We also use the canonical link tag, so that alone would probably be enough in most cases.
