I think that saying that a online community is implying effects to real life is a bit too far to say, but i understand how you feel.
I also can say that in many years, the internet has never saw a community like this before, and im proud of it, truelly proud.
But again i must say, let the internet and other strangers have influence on your real life is bad, really bad.
Of course, not always, but you have always to make sure that you're not falling into a psychological trap or a scam.
Being guillible is a fatal error sometimes, but i do assume that the most part of the community have enough common sense to avoid any sort of bad intentioned actions.
Share feelings, may it be happiness or sadness, is a great thing, i appreciate this part of the community, that's what make this place so wonderfull and awesome!
And i agree with you, ponychan is one of the greatest community on the internet.Arbor bona fructus bonos facit.
