io9 posted an article about e-smokes could use some comments from real users of PV's to set the record straight.
What you need to know about e-cigarettes
What you need to know about e-cigarettes

Good lord, some of the comments...
Seems like ignorance is fizzing apoplectic rage, rather than bliss, for some folks.
Yeah, that's more like what I expect from the average Gawker commenter. For cryin' out loud, even Farkers hate Gawker commenters, and you know you have a serious problem when Farkers denounce you.
Exactly the comments I was referring to. I toyed with the idea of posting a rebuttal, but then quickly realized that I had about the same chance of getting through as I did of keeping a jellyfish alive in a blast furnace.
Seems like I need to brush up on my Internet pecking order. I've never even heard of Gawker before now and I'm only passingly familiar with Fark. Though, when you said it's only a couple steps above Youtube in terms of comments, that made a lot of sense.
I still like Randall Munroe's take: "For fun, try to post a Youtube comment so stupid that people realize you must be joking. (Hint: This is impossible.)"
Pretty much, unfortunately.
Gawker runs a suite of sites -- io9, Gizmodo, Jezebel, Jalopnik, etc. Unlike more restrained sites like Engadget, Gawker doesn't censor its contributors and sometimes posts NSFW content that's only marginally related to the theme of the site it's posted on (like posting the tech of some sex toys on Gizmodo.) This, in part at least, seems to draw crowds from the less fashionable ends of the Internet and it definitely shows in the comments. That (and the format change some time ago) is what made me stop visiting Giz.
I still frequent Fark though. That's just a news aggregate site dedicated to collecting mostly the stranger stories and creating funny, usually snarky headlines for them. The commenters though tend to be quite snarky (darkly so at times) and home to a lot of memes. And trolls. But trolls are sort of accepted there and graded on the quality of their trolling, which tends to defuse the trolling's sting.
Yeah, just another relative of Poe's Law as applied to comments on the Internet.
That ArmchairZombieTherapist's guy, dear lord..
Quote- Sorry you got slammed by all the vaper forum members who came over here to defend their filthy habit and flame anyone who dared call them out on their rationalizations.
-Educating = flaming
Quote- Except caffeine drinkers don't rationalize their habit and blow their caffeine smoke in other people's faces.
-Who does this?, especially to this crazy shut in.
Quote- Rule #1: Never trust an addict to give you the truth.
-?, lying scum are we?.
Quote- Oh, you stepped in it now, dude. The vaper forums have been coming over and flaming anyone who dares to question the almighty e-cig, it's gross chemical stench, or their "right" to smoke in your face even though you have every right to be offended and concerned.
Awww, what are you gonna do, vapers? Are you gonna cry?
-LOL, stay classy..
Quote- Seriously, smokers and vapers are the "OBAMAS GUNNA TAKE YER GUNSSSS" of the drug world.
WAHHHHHHHH why won't people accept my addiction?????? wahhhhhh....
-What is he so afraid of??.
Quote- "HOW DARE YOU NOT FULLY ENDORSE AND CHEER FOR MY FILTHY HABIT!!!!!" - every smoker/vaper ever
-this guy has a serious chip on his shoulder
Quote- I even knew something was wrong when I kissed her the first time and her mouth tasted like chemicals. I asked her about it, and that's when she admitted she used an e-cig. She had never done it around me on dates, so I had no idea.
-This is a total lie, no woman would ever date this kind of person.
Quote- There's no excuse for smoking. It's a disgusting habit, and you're a bad person for engaging in it.
-Me bad?
Qoute- I'm not being self-righteous. Cigarettes are gross. The $100 e-cig my ex-gf used made me cringe when I had to give her anything more than a peck on the cheek. The taste was FOUL. She tried the flavors, and they were synthetic and FOUL.
We actually broke up over it. She choose her addiction over a loving, healthy relationship.
Folks, don't try to rationalize your disgusting behavior. Admit that smoking is gross, whether it's cancer sticks or e-cigs. Then do something about it.
-This is flat out trolling
The rest are just too vulgar to post.
What's your Fark handle? ;-)
