When I go through Google Reader each day, I tend to go feed by feed using the left-side tree-view of feeds. Sometimes (rarely) I use the “All Items” option at the top, which lumps all the feeds together chronologically. This behavior just struck me as interesting, because I used to think I would really love software that could aggregate all my e-mail, RSS feeds, news, etc., into one big list. I’d then be able to power through that list more efficiently. Now I’m thinking that wouldn’t work, that the context of each piece of software is important to usability. What do you think?
