Since TB doesn't seem too busy at the moment, here is an idea to consider. What if TB went through FT and somehow labeled threads that it considered to be extraordinary in some way. These could be highlighted in some way, maybe with an icon or a bolding or something similar. The idea would be to bring attention to threads that are particularly useful and should be recognized as such.

One of the comments I often receive from new FTers is that there is a morass of information on here, but it is often buried. New FTers often wish there was some way to "jump" to the real good stuff.

One of the comments I often receive from old FTers is that there is a feeling that a lot of good old threads get lost in the shuffle. Old FTers often which there was some way to "save" great threads for posterity in a high-profile way.

How good is defined would be up to TB. How you decide whether a thread fits is also up to you.
