Indifferent, I think speed reading will be a far more conscious way of assimilating knowledge, while photoreading seems to be less of a conscious uptake process. It is also a system, which integrates the full process of reading. I suppose there are other systems for reading, which are more known in the academic target market.
As for reading online, I do know that speed reading helps, but the conscious method (such as the one that Evelyn Wood uses) is not the actual process by which great readers read online.
It is random and topical - your eyes read what captures its attention most, forms the logic of the syntax, then you formulate an opinion to respond to it. For instance, reading this thread itself.
It's faster, and also because you can't stare too long before your eyeballs ache from screen fatigue...
