I've seen people use Partiko for quite some time. I downloaded it yesterday. I've been using it instead of a web browser on my mobile.
It is pretty elegant.
The gamification and points you get while using the app make me wish I had even more Steem Power to generously upvote and curate content.
The interface is a little confusing at first, in particular when engaging with nested comment feeds. I'd love the opportunity to turn off the Partiko signature, but I guess it's a little bit like people sending emails from their iPhone.
That signature... it's always there.
