I've been using it since I started using RSS/Atom feeds, which I think was around when I added a feed to my blog (about four years ago). In those four years, not too much has changed except the ability to share items with contacts. I think that's kinda Google's thing: make a really great initial release but then don't spend any effort evolving it (*cough* Gmail *cough*). I've followed you, and you can follow me back but I usually don't share things. I tried it for a while, but my problem is that I don't want to share something until after I read it, and I never actually read things in Google Reader (except a few comics). I'm not enamored with it, but I'm used to it. It's web-based, which is a must-have for me so I can read new stuff from any computer. I don't like that it only keeps 30 days of read/unread history, so if I leave something for a month it gets forgotten (you can still scroll down to see it if you click "all items", but it loses the "unread" flag). I also wish they'd just give a list of titles so I could just middle click on the ones I want to read. Right now I have to click the title to expand it, then my browser pauses for a half-second while ajax retrieves the snippet, then I middle click on the title, then I click on the thing to collapse the entry. And of course if the entry has a full summary, sometimes it causes the preview pane to scroll when expanding or collapsing the item, which means I have to move the mouse all over the screen when I could simply click on a list of titles. This makes it a little impractical to subscribe to a feed that publishes dozens of items per day (i.e. news sites like CNN or Joystiq) when you only want to skim the titles.
