So what we have is a timeseries of user-post pairs, and we want a good view for that, a UI that scales well to handle pathological cases. I like the idea presented in the article, but, as you mention in this comment, it is only the first step. Perhaps a library for creating good views for this model would be good, and it should have some good primitives. Then people can develop and share new views for social news. The article's suggestion would be one view, and maybe some of these views would compose (i.e., after the transformation from the article, a timeseries of user-post pairs becomes a timeseries of user-(timeseries of posts) pars, where a (timeseries of posts) is presented as the most recent post and a control with the cardinality of the timeseries as its label and a toggle-hide behavior, and that thing fits in the outer UI the way a "post" would.)
