I uploaded some interface changes recently that change some of the basic interactions. The disk icon was removed and a star added to the left of each item's title. Starring an item provides the same functionality that saving did before. This coincides with a backend change that is setting FeedsAnywhere up for future Google Reader integration. I'll be gradually adding to that capability so stay tuned.
In an effort to steamline the Title View for smaller screens as well as make the site more touchscreen friendly we moved the thumbs up and thumbs down icons below the description and enlarged them. This meant that we needed a new way to indicate interesting status at a glance, thus the introduction of the star's glow. Green means interesting, red not interesting, and no glow means it either hasn't been scored yet and will be in a few minutes of we are unsure which direction it falls.
