This has come up several times. I think we are a bit different here, and certainly at the Inn different. The Radavist is about selling "a dusted off retro look", whereas here, it's the real deal - with all bits and bobs, flex, breakages, heart-aches, wrestling and obsolete-ness. If anything, RB is probably influencing Radavist but the chances of anyone admitting it over there is zero in my mind.
The Inn is a big melting pot. While there are regulars that specialise in various things to share knowledge, time periods, disciplines, etc. there's pretty much an overwhelming ethic of being tolerant and being open to other bike types and periods just for the love and understanding of bicycles. Several people have gone out of their comfort zone and many have learnt a lot about just how rich the world wide bike culture is.
