I'm getting in the habit of "feeling" posts with my mouse to look for links. I've tried underlining or coloring them, and that doesn't seem to work either.

Punching through those internet "tunnels" is part of the trick when doing research. It's particularly hard when one source or meme is saturating the system. For example, try finding older news stories about someone who just made recent news. Fortunately, Google has a primitive "older entries" function that works fairly well, but you still have to filter out a lot of "digest" sites.

Another trick is to find a peculiar phrase or word combination from the current story or meme and subtract that from the search. For example, to find older Arnold stories, a good start would be to subtract the word "baby" from the search.
