I enjoy reading the spotted threads on the web site.
They are always good.
Is there a way to go back in time and see very early threadspotted threads?
Please see here: https://www.straightdope.com/threadspotting/
You get there from The Straight Dope front page by clicking on the “Threadspotting” header.
You can also submit threads you come across in your travels on the SDMB for consideration for Threadspotting. Send your submissions to nominations@straightdope.com. List the thread url, write a tag for it if you like, and how you’d like to be credited.
On rare occasions I find ancient Threadspottings that are still good and worth giving a rerun. When I do I bump them so they can be enjoyed by what is now a new generation of Dopers. I need to do that more often.
