You mention that you don't use speed-reading techniques. Is this because you find them ineffective, taxing, or unenjoyable? My understanding (based on working in literacy tech) is that many speed-reading techniques — esp those taught in study skills classes — are more akin to skimming than what educators call "close reading". On the other hand, there are tools like Spritz [1], Spreeder [2], and BeeLine Reader [3] (of which I am the creator) that are aimed at increasing reading speed, but which are very different from classical speed-reading techniques.
Since you're interested in reading, I'd be interested in your take on why you aren't using classical speed-reading techniques, and if you find the tech tools to be objectionable/not worthwhile for the same reasons.
