I could compare this platform to Imgur, another media sharing site, but tailored to artists. For some reason, it's way easier to spot the more questionable content than art with more effort put into them (this includes the art piece itself, as well as the content in the description). I could describe it as "freer" than other artists platforms, as there are LOTS of ways to communicate with everyone. About a couple years ago (I'm sure it was way longer before) I noticed they started to mimic Facebook status sharing, which I thought was a little strange. Even the polls thing is kind of an excessive feature to have. I understand it's all meant for more community involvement, which has happened, but there's also the responsibility of the website host as well as the artists to maintain and encourage composure throughout the community. There is a LOT of blaming and blame mongering (as you can see here). There will ALWAYS be people we like and dislike. Your success (whether it's your favorite count, watch count, etc.) on this website WILL NOT fall at your feet. This is a website where you must involve yourself in what the website has to offer and supporting other artists will help the site immensely, believe it or not.
Ultimately, this website is like the gateway to the art you really want to do. If you feel you already have your skills honed, I do suggest tumblr, Artstation, or Pixiv (japanese based), even Facebook. DeviantArt can help increase your fanbase if you understand its quirks.
