When searching for "weather [zip code]", I have the option of adding that info to my Google homepage. If people cannot reproduce, I'll grab a screenshot.

This could potentially be the start of allowing you to aggregate search results on your homepage.
-search for an rss feed and add it
-have a gadget of the search results for a certain term
-others?

"aggregate search results on your homepage."

How can this be .. results ?? The option here is that you can install a google (offical) gadget on /ig. Lets say I find a new blog, can I auto click and add to my gReader gadget on my /ig reader tab ??

oh and I ust noticed that the default on my Google Groups is being set to
"You are not a member of any groups."!!
