It's not just about being passionate. I live in a country where consumers can no longer (i.e., since 17 January 2017) buy vaping products online so it's also about watching how people vape in person, being allowed to give their vape a try, and talking to them face to face as opposed to reading what they write online, visiting places where high wattage vapers, mech users, and coil builders meet up and show you what they've got under the hood... it's a friendly little atmosphere. If you don't visit such places very often, then you can't very often learn from those who don't usually share a lot of detailed info or in-depth knowledge online. At my go to B&M store, there's always an experienced mech-using professional coil builder standing behind the counter excepting only when both of them have called in sick. The shopkeepers also own a wholesale company of vaping products, BTW. The vast majority of other shops don't cater to a wide variety of vaping styles, or they barely try to, and, knowledge about vaping products that aren't just another money grab tends to be extremely limited in most other shops. Not every new vaper finds the luxury to enter a decent shop or receive unbiased info online. A lot of mediocre stuff gets overhyped, just like a lot of good stuff gets underrated, when most online reviewers only vape for half an hour on the products before they review them. The same also applies to users who voice their opinion before they put in real effort to learn how to use a product.
