Part of it is TLS's web design, particularly on mobile/tablet. I find multi-column layouts, especially where content fights with adverts and distractions (even just on-site elements) for attention, to be grossly suboptimal. Unfortunately, TLS fails both Outline.com and non-JS console browsers. I ended up copying text to a console pager to read it.

The style and content also contributes -- the review itself is ... eminantly skimmable.
