Why does someone go to the effort/expense of doing summaries without adding tags? The goal is less slop and not more, and this really just hurts usability after you've already spent money that could actually help? Isn't this the whole value proposition for literally everyone or am I nuts? I don't want a summary. I will switch immediately to the first alternative that allows tags/categories/filtering.
