As long as you can vaguely remember where you read X thing, you can always go pull the info back up. That's part of the reason I aggressively use social bookmarking services (namely, Diigo).
I also find it's helpful to have a high-level understanding of many things, especially when it relates to technical "stuff". If you have some understanding on how/when to apply an approach or technology, you can always dig up the details when it is pertinent.
