Photos of mods coming off as boastful is an emotion on your side of the spectrum. If someone asks for someone else's setup, and then that image is promptly shown, I don't see how its on their side of the fence to feel boastful about devices that they use daily. What works for them, works for them. What they're willing to spend the money on doesn't matter in terms of how happy they are with the devices and vaping performace they are getting. What you should focus on is whether or not you are happy with your PV's and how happy they make you. I find it nice to see what other ideas other people had and how they are achieving their favorite vape via the devices they own.
And if they do feel boastful, well, good for them. I see no reason why any one person shouldn't feel good or proud about items they spent money on and enjoy using. I like feeling proud about the mods that I own and I don't see it as a drawback to show off every so often, even if I'm not really showing much.
I understand where you are coming from and also how I came across in the original post. It was not my finest moment as a poster and I think I hadn't had anything to eat practically all day, also, I was going through a parallel situation at work, that by the way, no one would applaude.
