Problem? Perhaps for this fellow and some others. They might might not be aware there are those who don't care for the social side of Google Reader and use it as a place to keep RSS feeds in sync.
Actually, I only made light use of Reader's social features. Aside from their absence (which I do think is a shame) the visual changes to the more newsreader aspects of Reader severely impact the product, and are a big part of what I want to repair.
