Yeah, I had that feeling when I first joined, I didn't really know what to post about, and heard people saying to find a niche, but I wasn't too sure what mine would ever be, so just got on with it. It was about 4 months into being here that I started writing fiction, and since then that has been my main focus, it's the first time sharing stuff publicly and the feedback I've received in the last year and a half has been amazing and I feel like I've come a long way in my writing.
I've also gotten to meet some really cool people on here, I've never really been a big social media person, I have an Instagram, but rarely post on it. I like it here though, and to be fair, whether it becomes this big mainstream thing, or stays semi-underground, I'll still be here.
"Find a niche" was hard for me, and as time passed I think I just made my own. I see things differently than most here and do things my way. Not everyone likes it but that doesn't matter. It's for the people who do. My most recent post was fiction. This one wasn't. Before this post I did some rhymes that built up to be character development for some art. But I'm not the artist that puts their work in a gallery. It's all comic/cartoony stuff. My own style. Underground as fuck and I kind of like that.
