I haven't made up my mind yet. However I can tell one thing that annoys me (and perhaps other people as well) about infinite scrolling (specially on on web) is the state.
You scroll and scroll for content, you find something relevant and click on it to see more details. After you are done with it you go back to the list... the problem is that most of the time that list gets refreshed so you have to do all the scrolling again. I guess the best way to fix this would be to store the state of that feed to avoid this issue.
