I agree that the standards have gone up. I think we have more people posting than ever, so the good stuff is bound to show up more frequently. I remember someone posted a RLPL plaid sport coat a while back that got zero comments.
I like the growing appreciation for more vintage stuff here. Sometimes a 1950s Deansgate jacket is more interesting than another 90s Zegna suit. I hope Spoo's vintage thread continues to take off too.
You're right, more people leads to more/better finds. Naturally we get desensitized to certain labels, though I'd certainly be excited to find any number of them. I think I know the jacket you're talking about - I saw it on my phone and thought it would be quoted 5 times, but nothing else had been mentioned!
I love the vintage stuff and most of what appears in Spoo's thread. I absolutely love some of the stuff from the 1900s-1960s. It's fairly rare to find in thrifts now, but I'd guess it will be incredibly difficult in 5-10 years. Of course the stuff from the '60s and '70s will appear, but the old generation from WWII will be gone and the last of their clothes donated.
