I would suggest providing a hint to the remote content. For example, if it is an image - state it, maybe with a preview.
It would also be useful to filter out 'tabloid' sites like reddit (or restrict it to /r/programming /r/sec etc).
Some mechanism to preview content or view their content in a consistent style would be nice as it can be a bit jarring going to Slashdot from an otherwise clean interface

Probably worth mentioning the labels on the left don't seem to do anything on chrome and if you resize the background remains at the same height.
If you're going to display how many comments there are on an item, please make that linked to the actual comments so I can read them. Besides that, it looks nice! Good luck with it.
