In Google Webmaster Tools, I often see duplicate meta descriptions that come up when a person quotes the OP and it's at the top of page 2, 3, etc. For example, let's say this topic flows over 2 or 3 pages. If someone quotes my post at the top of page 2, XenForo will show a duplicate meta description. This is auto-generated, but it would be idea if it would ignore quotes. I think it would cut down on duplicate content errors showing up in GWT.
