I just love this back and forth and openness within the Google Talk Team check out the last two posts on the google talk blog – http://googletalk.blogspot.com/

They are talking about notifications in Google Talk. Here's a snippet of it

Joe Beda, Google Engineer:
--Over the next couple of days, there was quite a bit of discussion about whether this feature was a good idea or not. Jon Perlow stated: "This is the worst feature ever. Shut if off please."--

Googler Jon Perlow Responds:
--In response to Joe's post, yes, it is true that I said "This is the worst feature ever." Unfortunately, my passion often gets the best of me and I am prone to hyperbole. What I really meant was that I think the feature can be a lot better.--
