I do this too (although I think of it as a "backlog" rather than "hoarding" but it's not important.) Two things seem to help: 1) Filter by "actionable"-ness: I ask myself, "Am I ever going to do something with this piece of information?" 2) Jotting down a sentence or two per item that captures why I find it interesting. Even that much work can change a list of tabs/URLs into something more like a useful directory of information. Hope that helps. :)
