I joined steemit because of @Crypt0. I heard him say the name a few times on his YouTube channel and it just sounded so interesting. So, I joined and haven't looked back. I've never been one for blogging, but the steemit community is so friendly and welcoming. It almost feels like I could post anything and that feels great.
Aside from that, I believe in the Steem crypto currency and I feel like it will continue its upward trend. We all go to the moon together.
