Of course, speed reading gets some meaning lost. But the very skill of speed-reading amounts to developing a sense of look-ahead: first, intuitively establishing fast anchors in text to actually read a few moments later; second, to expand on this anchors, absorb the information and introduce feedback corrections in look-ahead patterns.
All my reading is "speed reading"; I even can't follow the linear text word by word anymore, this is way too boring. But I can regulate the time distance between look-ahead and absorbing passes, and thus the ratio between speed and meaning extracted. This is invaluable to find something in technical documentation, or prepare for exams.
And I can't listen to audiobooks or lectures; they are sooooo slow...
