While it is theoretically possible to check for "Had Interesting Moment" fields on a lead on every page load, this is going to incur a lot of overhead. I wouldn't advise this.
Rather, since you're talking about the known browser history, just set a cookie when they visit your interesting page, then look for that cookie on every page load (or set localStorage -- same idea). Marketo doesn't need to be involved.
