For stuff I need all the time (wiki's, forms for work, code repositories), I simply use bookmarks. For ideas / notes, I email myself with "idea: <...>" or "note: <...>" in the subject and have gmail stash them under labels for this purpose. So for example, if I came across an interesting article that raised some questions or that I might want to discuss with someone later, I'll put the link in a note to myself. I admit it sounds a bit crude but gmail search is really powerful; I can usually find things from years ago with only a vague query. I can come back to the note later and amend it by just replying in the thread. Moreover, "collaboration" is already built-in: just cc a friend. Finally, the medium is not limited to stuff I found online; I can snap a picture w/ my cameraphone/screenshot, or write up some LaTeX equations to scratch down a back-of-the-envelope calculation. I've tried Evernote, but I just couldn't get into it. It's a whole additional app/browser extension that I have to worry about, and requires a context switch. I'm already in my inbox all the time throughout the day, so it's a no-brainer to use it.
