Initial sketch:

Improved sketch:

Bob would read through his news items using this interface. He would use 2 fingers to scroll up/down looking to look at the news items. He could tap on the "tag it" button to mark items with predefined or Bob-defined tags. He would use the "share it" button to share the items in the feeds he made available in Hubbub (like Facebook or Google+). The entries are "cut off" if they are too long, so Bob would have to tap them to expand or shrink them accordingly for reading. If he wants to defer reading certain items, he can use the "later" button

The political article would be long enough to be cut off, but he could read all of it by expanding the article with the disclosure triangle. He would hit 'save later' when he decided to read it later, which would cause it to show up in this stream again some time in the future.

He would share the imgur image by pressing its 'share' button, and press 'tag' to put it in the 'cool' category. The tag button would be come 'add/edit tags' after there are tags assigned.

Items would be marked as read automatically as he visits them.
This may be too low level, but I want to note this here:
This interface does not show what happens when you are done sharing or tagging an item. There will be visual cues saying what happens. For example, changing the "tag it" button to "edit/add tag" or something, or changing the "share it" button to say "share again". scrolls past them. 

This interface is very similar to ones people already use to view information (Twitter, Facebook, reddit, etc.). In addition, this the vertical list format is very common for on phones, so Bob will have little trouble learning how to go through his news items. However, with this interface there is no way to remove or "hide" items from his feed (a feature found in many applications).  

It is very efficient for reading items. Bob can quickly scroll through and skim the first line of each entry as he looks for things to read. However, If he wants to mark multiple items at once (such as read or read later), it will not be easy or quick to do here. Also, it is not clear if Bob has to click on entries to change focus between entries (will every button on the screen be accessible through one tap on the phone? Or will Bob have to tap on an entry first before he can use the buttons?), it will not be easy or quick to do here because he has to do them all individually. Having the buttons always visible may mean more scrolling is necessary, which could slow Bob down.

Bob can easily expand/shrink entries. With this interface, items are currently not deletable, which avoids Bob accidentally removing something he wants to keep. If Bob doesn't like a tag he put on an entry, he can edit or remove it using the "tag" button again (though this is not clear in the drawing).
