Google Reader mobile removes an annoying step
At some point in the last few days Google fixed one of the most annoying things about Google Reader mobile, namely that it didn’t automatically take you back to your list of feeds after you clicked mark all as read, but instead just reloaded the page sans posts (if no unread items remained). That one extra step (i.e., having to load an effectively empty page) could make you want to pull your hair out, especially when without fast connectivity.
Also, the 20-item mark all as read issue has been remedied as well.
