So here's what's worked for me over the years -

I collect interesting links/pages/stuff by emailing myself notes about them. I never actually _do_ anything with these notes, but from time to time I open the "Notes To Self" folder and skim through them. Anything that seems worthless I delete, anything that seems obvious I delete, the rest just sit there.

And that's more useful than you'd think - by reviewing them semi-regularly, you're indirectly memorizing their contents and refreshing their presence in your short term memory. And that to me is the benefit - not "copy this cool thing", but "feed my mind cool ideas until it has digested them and incorporated them into the gestalt.
