Rolling back the "Who's reading about" module on Pulse pages

We are rolling back and disabling the "Who's Reading About" module on the pulse pages, as it hasn't performed as well.

The feature is also consuming a fair bit of computing resources, and causing a substantial increase in server side latency ( which went from ~500 ms to ~700 ms ).

Being a small startup, we have the ability to experiment with new ideas. But when something doesn't work as well as expected, its best to prune it out. It helps keep the product lean, as well as frees up space and time for other ideas.

The Geo-Popularity Platform on which this feature is based will continue to be developed. We have a few things in the pipeline, which we hope to unveil shortly.
