I haven't really got much to go by, but I just had a quick look and it doesn't entice me to use it.
For me, it's just the layout, it hurts my eyes.
But the references to 4chan aren't putting it in a good light for me, I was on Tumblr a LOT when they tried to 'hack' it, and some horrible things went on. Any site that has a NSFW section scares me, haha.
I am way too addicted to TBT, so anything that isn't TBT is just...no.
tumblr has so much NSFW content haha
I honestly don't even know what it is.
^ I can't tell if you're spamming for more TBT or trying to be funny... either way, it's kinda annoying tbh.
Anyway, Reddit is decent. It surprises me that there are actually decent sections on there. I honestly expected it to be total trash when I visited but... it wasn't. It blew my mind. O_O
The community is generally very kind if you are talking to the right people and know where to look. Very helpful too. The reason why a lot of the negative aspects of the community shine through is because the founders (mostly) believe in full free speech on the internet and reddit is supposed to be an example of that. That's also a reason people were mad that a few subs got banned - they thought it was an intrusion of free speech, although it was just because some people of that subreddit were attacking specific people which is completely against site rules.
