Listening to the MACNA video above struck a chord with me b/c I have been that new employee that was trained my folks making this hobby their living. We did our best to bring those new customers in and still make sure we could square away the more advanced hobbyist as well. I think sometimes we didn't do a great job of either of them and left this vacuum where everyone in between beginner and advanced fell.
Retail is changing and I think the way forward is to think about brick and mortar differently. As the hobby has changed and continues to change I think there are creative ways to keep the folks that surf here on R2R engaged at the LFS, as well as bring in new hobbyists. Creative sourcing, trade ins, etc.
How to be different, unique, but not so niche? Having enough of what everybody else has but having a unique enough selection that you aren't going nose to nose on every product with every other online and brick and mortar retailer? It's a fine line to walk.
Sorry to ramble on, had a bunch of thoughts rolling around and didn't do a great job articulating any of them.
