Parsing only the first 100 entries, I found lots of 404s (page not found), and both 301 (moved permanently) and 302 (found somewhere else) redirects. Site owners get their sitemaps declined for less invalid entries. It seems Google does not use its own XML sitemap.

Dear Google, please forgive me. I just had to publish this finding ;)
