Awesome! Glad to hear that you're loving your time here. I'm in the exact same place, hardly browsing Instagram or Facebook anymore. Especially with apps like SteepShot which basically replaces instagram with an alternative based on STEEM, why would you keep on using Instagram?
2018 will be huge for STEEM. Just looking at their GitHub today you can see how much work is being done to wrap up the new communities features. We're only going up at this point :)
