Everytime I use a browser to get the http://amoderatelife.com/sitemap.xml.gz (after referencing the robots.txt)

I can't get any browser to open it properly. And Yes, I know its compressed, but other sites I've seen with compressed Sitemaps display properly.

Do you have Compression enabled in apache for this site?

Now, I can download the file and open it just fine... which leads me to believe, browsers can't/don't know it compressed. Which also means search engines... won't know either.
