I don't mind the Pocket button, but Pocket shouldn't be considered a replacement for RSS/Atom. People need to be able to choose what information they consume, not leave it to algorithms. Algorithmic news feeds are one of the current problems with information on the Web.
I hope the browser will still suggest feed-reading extensions when users land on feeds. Not doing that would be shady.
I also don't mind the pocket button and I actually want to use it to save my bookmarks. But two things are making that hard for me:
1) My employer has disabled the button in firefox. I can work around this by signing in in any browser but there is something weird that happens. I think I have to allow all kinds of google javascript spyware to run some kind of captcha to be able to sign in.
2) The saved links do not refer to the original sites I've saved. They are some kind of click-through tracking spyware.
Also the tagging feature seems hard to use. As I recall it seemed difficult to filter using multiple tags.
If it was more like Delicious I'd be happy with it.
