The new approach for generating Google Sitemaps support dynamic Google sitemaps - and dynamic HTML sitemaps.  This can be great for smaller sites, but may cause problems for large sites that need to compress the Google Sitemap (when the sitemap is larger than 10 MB - yes, I realize that's HUGE).  Dynamic generation also limits the flexibility a webmaster has in controlling what is included in the sitemap, including the last modified date, change frequency, and priority.  Of course, if your site has thousands of links, you probably don't WANT to review and edit every link.  I'd like to get your thoughts on which approach to take using the attached survey and the nukeSEO forums to comment.
