They've obviously put a lot of work into Reader, and use it every day. One problem remains... if I find a web page that I wish to "share", "like", or make notes about, but don't find it via a feed, the Reader features are all useless. Google Notes, Blogger, and Orkut would all be better for those tasks, but those products are either discontinued (Notes) or fading (Blogger) or fading fast (Orkut).
