Yeah, this is the only way I keep my browsing sane. Over the years, a kind of "tab garbage-collection" habit has emerged. I find it works really well, since if a tab hasn't been visited in the last 20 minutes, I probably won't open it again.

Additionally, the history-tracking of the browser is good enough and my google-fu sufficient so I can find anything I need that I've previously visited.

Keeping my tabs lean makes me much happier!

I've found Evernote with it's web clipper to be great for this. Anything I figure I might want someday, but I don't know exactly when or why, goes into my EN archive. The full text is searchable, so it's like having Google for only stuff that I've found interesting in the past. (And the clipper can even add results from your library to search engine results, so you can re-find things even when you're not specifically looking.)
