I like use the Google sidebar as my simple, stupid news and RSS reader. However, one thing I find annoying, -- ok, two things.
1) No ability to import or export feed lists! I have feeds in my RSS readers and other websites in OPML and other formats. Is this possible with an extension? I'll have to look around
2) The automatic of recent clips is annoying and leads to a lot of low-quality sites being added to my web clips. One of the first things I did after using GDS 2.0 for awhile was turn this feature off.
More on vertical search and other things soon to come ;-)
