I think that image boards, like all forms of social media, operate as an artificial simulacrum - a supplement for real life social interaction. So I think once you have a robust social network there's not a real need for online social life and that osimulacrum becomes a complement to that social network or becomes redundant. The lack of third spaces IRL is probably one of the reasons so many have turned to online social networks as a substitute. But there's already too much negativity and misguided nostalgia in this thread so I'd rather not continue on that. "Pessimism leads to weakness, optimism leads to power". I think that the appeal of these virtual social networks is that they can compelement and extend existing physical social networks, and that in the absence of physical social networks they can offer a supplement that can potentially blossom into a physical one as well. We have a thread actually where sushis connect and meet up in person! I think that only really applies to social media websites with a positive atmosphere though, so even with virtual social networks you should be careful to choose your friends wisely.
I like the comfy culture of sushigirl and I like supporting and being a part of the positivity because I know it is helping other people. Also because I know that everyone in here has a unique and interesting life, and I like being involved in the tangle of people's lives. That's my reason to come here on occasion.
