Capacity
A vexing problem for any knowledge worker (i.e., a person whose job involves handling or using information), is the corralling, filing, finding, structuring, reading, retaining and otherwise accessing and using that information.
There is a lot to that sentence: there’s the 'organising' and 'storage' of information and knowledge; the 'using' of it, and the 'temporaneous-ness' of it (I just made that up. I mean timeliness, or, right information, right time).
Faced with the overabundance of information, many will skim through information. Some though, will read thoroughly, question it, nit-pick, and basically tear it apart. The world certainly needs all types.
