Micro-blogging site Twitter has begun testing a potential new feature "custom-built timelines," beginning first with one focused on The Bachelorette.

According to The Verge, the idea is that they are topic-focused timelines users can swipe or click on from their main feed so they can scroll through the conversation about a specific subject.
