It is indeed. Before looking at this thread for the first time 6-7 months ago I had amassed a fairly sizable collection of ties, none of which were Hober. Since reading/viewing this thread, I have now amassed a pretty sizable Hober collection as well. There are at least two "problems" with this (1) I continue to see ties on this thread that I like and must have and (2) I am almost completely neglecting my non-Hober tie collection. So it bears repeating, "this thread is dangerous".
Other than the effect on one's wallet, I see no issue with (1). I also see no issue with (2) as every tie I've worn this year has been a Hober. I think that joining the no purchase club for a couple of months might be a good way to stop the madness.
