google blog search and AtomEnabled

for my bloggin friends: Google has released the beta version of their blog search.
Here is a link:
http://www.google.com/blogsearch
If you do not publish a site feed for your blog, it will not be included in Blog Search. However, if you previously published a site feed that was included, the old posts will remain in the index, even though new ones are not added.
Blog Search will also respect robots.txt files and NOINDEX, NOFOLLOW meta tags

here is some information about Atom Enabling:
