I use Evernote (for notes) and Dropbox (for files). What helps me to stay on top of things is that I write everything in Evernote myself and then add the references at the bottom.

First, that helps me to rephrase knowledge in my own words (except for quotes, of course), which is good for retaining knowledge.

Second, I use tags and note links that help me to navigate through pieces of knowledge.

Third, I only store files in Dropbox, with a very well-maintained folder structure.

I don't clip stuff in Evernote and don't just copy/paste. I think that bloats the whole thing up and makes it unnavigable.
