Are they expressly illegal? Frowned upon? Out of favor among the SDMB proletariat? A TMI thread helped bring me onto these Boards, and I kind of miss them.
Personally, I would like an entire forum. Upon which I would gaze and awe.
I haven’t seen any announcements that they’re not allowed, just some of the grumblings about the content. Then again – if you don’t want to know the TMI details, don’t look.
There is no such thing!
If history is any guide, then this is the deal: TMI threads are not expressly prohibited; one or two, every now and then, is okay. It’s only when the positive feedback loop gets out of control that it becomes a problem. In other words, when all of us gleeful little monkeys get overstimulated by one “ever had a big zit on your BUTT?” thread and start half a dozen similar discussions at the same time, that’s when the mods get a headache and shut 'em all down with a growl.
In other words, in my view, if you really want to discuss your anal fissure and the taste of your earwax, then discipline is the key, grasshopper. I await correction by the powers above.
In addition to the wise words of Cervaise, my (non-mod) contribution is it is highly polite to clearly label TMI threads with TMI in the title, lest the unsuspecting stumble upon your proctological problems to their deep dismay.
This pretty much nails my feelings about it.
