A couple scenarios for how I get a lot of tabs open:
- <ahem> Hacker News. Scan down the page, and for each interesting article, middle click the article and the comments link. Work your way through the tabs (maybe going back and forth between "work" and HN).
- Search. Middle click the most promising results. Work your way through the tabs, possibly bookmarking something that you know you'll want again.
ReadItLater or any other temporary archive seems like procedural overkill for something you intend to come back to in a few minutes to half an hour.
Bookmarking the same sort of material seems inappropriate since most of what's in those tabs isn't yet determined to be bookmarkworthy.
I didn't dream this up, it's just how I naturally organize my short term browser use. I think "short term" is the important phrase there.
Finally, there's a middle ground between lots of tabs and ReadItLater. Chrome has a nice extension called Session Buddy, that records the tabs in your current session. Hit the button and another tab (ironically) opens, showing your current and recent sessions. Now close as many tabs as you like, get back on task, and gradually work your way through the sites listed on the session buddy tab.
Lots of ways to do everything. I really don't think I'm nuts for doing it this way.
