I haven't dug too far into it myself, but I've been including the palnet tag on stuff I would have been posting to the blockchain anyway via dTube and Actifit and I'm liking it so far. Having a less top-heavy distribution of voting power is making me feel more positive about the economy than regular Steem, and the positive energy from all the enthusiasm and excitement associated with the new thing is nice.
That's what I generally feel about it too. It's like a second layer of Steem, and it offers a little more consistency and opportunity for the people who missed the big Steem event.
