"Brad Bortone is an writer and editor, who brings 12+ years of experience to the table."
Just goes to show that long experience doesn't guarantee an increase in knowledge. I've known people with less than a year's experience who could fully master a subject in which another with over a decade of experience could barely attain a basic understanding. Unless Brad Bortone is lying in his article and knows considerably more than he demonstrates regarding the properties of e-liquid, then he's one of the latter.
I've only been vaping for four months and I've learned by my own hand several aspects regarding the nature of e-liquid which defy several points in the article. In my experience, some e-liquids need no steeping time, meaning that I detect no change in flavor between the day I receive them and up to four weeks later. Others absolutely do change their nature after steeping.
There are several factors to consider, one of which is how old the e-liquids are when you receive them. MBV, for instance, makes theirs the day you order them, so I've learned that more of their flavors benefit from steeping compared to Halo flavors I've used, for instance. Thankfully, my very favorite flavor - Black Ice by MBV - tastes the same to me the day I receive it as it does up to a month later. I didn't pick it as my favorite just because it's one that doesn't need steeping. It was just a happy accident that it worked out that way.
If Brad Bortone didn't learn even the very basic fact that there are some quite popular flavors of e-liquid that most certainly do change their flavor after steeping, then he is really not paying attention. Or he hasn't tried enough of a variety of e-liquids to be able to knowledgeably comment on the matter.
You can't scoop a glassful of ocean water and, seeing no fish in it, surmise that there must be no fish in the ocean, can you?
