I recently joined Zappl too and I love the functionality and diversification it brings to your social media account here on Steemit. With Steemit it feels more like a blog posting articles and videos, etc. having Zappl in addition provides you more of a Twitter like addition to your account to provide general updates, feelings, questions, even photos and videos too and the tagging is super easy using hashtags.
I'm a huge fan and I plan to be a big user of Zappl.
Thanks for sharing because I'm sure there's still a ton of people that aren't even aware this exists.
