And then hope their blog doesn't disappear from the 'Net before you finish digesting or need to refer back to that information. Buy their book if they have one.
The founding goal of Stack Overflow was literally "programmers seem to have stopped reading books"[1]. NOT "programmers shouldn't read books", or "book learnin' is inferior to superficial familiarity", but simply... "they appear to have stopped". There are probably a lot of reasons for the tendency folks seem to have of not investing effort into building a deep understanding of the things they're working with... But ultimately, it doesn't really matter: either you provide information in bit-sized chunks, or someone else will and you lose the ability to influence the quality of that information. Not the choice we'd like, but the choice we have.
