I think it depends on the type of feeds you subscribe to. Some big news sites have multiple posts an hour whereas many personal blogs don't post in the average month. Personally I do more of the latter and probably get less than 10 new items a day (and 3 of those tend to be comics which are quick to read over breakfast). Often the higher-volume feeds that I subscribe to are filtered by author or category to focus on what I am really interested in.
