As in, did you ever come across a post or comments on a post that was NOT your own, but left a lasting impression or changed an outlook you had on things? In a way that had some real effect on your everyday life sometime?
just to give examples:
reading something about relationship stuff on IIN, then using that information in a real life date?
reading something about a fetish you also have being rather popular, thus finding the courage to bring it up to a partner?
reading a poll statistic and use the information it had to base a decision in offline life on it?
As said, it's specifically about OTHER peoples posts, not your own.
If you feel like it, feel free to specify which post had the most real influence on you and how so.

This girl had kept up with updating her post, updating her condition, and her thank you to the IIN community choked me right the hell up. Just knowing that she beat anorexia because of what people here did for her... I hope this site has helped many more people.
No, wait, don't answer that, i don't want to know :D
I've learnt a few things from individuals and got to understand a bit more about things I haven't experienced (contrary to popular belief, I don't have a friend or ex-girlfriend for every single situation. :P Although I do have many and have seen too much first-hand).
Learnt a bit about pack mentality too. It's very interesting to just watch IIN sometimes. It would be even more interesting had I never posted anything myself. I sometimes see people answering questions based on my earlier answers, which is flattering but slightly weird to me. And I sometimes see things happen where I think (rightly or wrongly), my influence was involved.
In terms of a single post, though, only one comes to mind. Normally insults rolls off my back. Something would have to be exceptionally vicious and cruel to get through but something did and it did change me. If I was terminally ill, I probably would have talked about it here. But now, I wouldn't.
That's one thing that I like about this website, the diverse opinions. I'm 20, and I believe that I have much time to solidify my opinions so in the mean time, I am giving myself room to "find my way", so to speak. I have established many beliefs already, but having many diverse friends IRL and hearing diverse opinions here puts my base of knowledge and truth into a state of fluidity in which I am willing to accept different opinions as plausible as opposed to fearing them.
What has really struck me is issues of sexual preferences and the way some people conduct themselves sexually as well as issues of tolerance and I feel that the more I read and explore, here and everywhere else, the closer I come to the truth.
*silly combat-ready pose*
Nora is MINE!
She even told me i could be possessive about her, so i'll not back down! You want her, you have to go through me...or rather, because that would be too easy, you need an OK from me AND her. Fat chance of that happening, so back down....BOTH of you.
you can sit over there and look at her and her posts from there as long as you're a good person.
but i'll not take it well if someone is using posessive word elements like "Mine" or "my" in regards to MY preciousss....i mean, my Nora.
You know the phrase certain lads use out on the town whilst drunk? "On the hunt for cunt". I guess if you're 'on the hunt for cunt', you could be described as a cuntsman?
only, the same thing happened to me, and i'm pretty certain it had no effect on my offline life, and i doubt it had for you :D
Hahahahaha, just kidding!
I get to steal a few minutes from work every now and then though, haha >:)
I don't even remember who's turn it was, mine or yours?
There are some users and/or comments that irritate me based on their lack of evidence or common sense applied to the argument, but thankfully there those intelligent ones who balance it out.
I registered an account here and have wasted countless hours on this site since.
In the past 5 months I've probably wasted over 300 hours here.
I feel so much better now than I did about half a year ago.
I've also learned quite a bit on here.
There are a lot of good comments left by users on this site.
