Max - good answers re: caching concerns. That leaves studying if the bytes transferred on average mobile article view increases or decreases with lazy section loading. If it increases, I'd say this isn't a positive direction to go in and stop there. If it decreases, then we should look at the effect on total latency, number of requests required per pageview, and the impact on backend apache utilization which I'd expect to be > 0.
Does the mobile team have specific goals that this project aims to accomplish? If so, we can use those as the measure against which to compare an impact analysis.
