Using e-cig forums as a measure of e-cig marketshare is like using headphone forums as a measure of headphone marketshare.

Most people don't have Sennheisers.

But my totally scientific survey of the Head-Fi forums says you're wrong!

Maybe it is, maybe it isn't. One key difference that comes to mind: people that buy a pair of Sennheisers doesn't typically run out and try and convert all of his friends and relatives who are using Beats, whereas with ecigs it is quite common (maybe because in this case it involves, you know, life or death).

seconding your anecdote. I use an ecig myself, and I live next to a college campus -- I'd probably say I see about five people a day using them. I have never seen someone using one of the cig-like disposable types.

And college campuses (and the areas around them) are totally a representative cross-section of the general; population on all things, including mechanisms of tobacco consumption, right?

Do you have reason to think they wouldn't be representative?

Your tone makes it sound like you're kind of hostile to the very idea, do you have some personal attachment to the matter?

> Do you have reason to think they wouldn't be representative?

The fact that they are demonstrably not representative of the general population by age, income, education, or, really, just about any other variable that has been studied makes it very unlikely that they'd be, except coincidentally, representative as far as purchasing patterns for any particular good for which a variety of options exists (unless its a good purchases nearly exclusively by college students, but that's clearly not the case here.)

No doubt. After all, it plainly doesn't suit your prejudice on the matter.

My prejudice has no effect on reality though, does it? So what is the reality?
