I went for a 300 LEO Power Up Day today, slightly more than usual because, well, LEO is 50% higher on Hive than it was just a couple of weeks ago, so better honor it I thought!
That's on the alt 
Of course the immediate reason for this is that Leo Ads are now live and buying up LEO, pushing the price up.
But that's just the immediate reason, the result of months of quiet behind the scenes development so that we are now in the VERY early dayz, I believe, of something of a virtuous circle on Leo....
If you read this post on Re-introducing Leo Ads Revenue it gives you an explainer of what's occurring...
Three reward pools...
The first I guess is the regular LEO that goes to content creators via curators.
To summarise what is a pretty technical process for the 'second reward pool' (read the post for the details, please!) ad revenue makes it way to the 
Basically the larger your LEO stake, and assuming you are minimally active curating on in-Leo, the higher revenue share you get from that Leo Ads rewards pool.
And EverGreen rewards....
This is a third rewards pool....
A small percentage of the LEO rewards pool above will go to content creators who published through InLeo and are above a threshold for minimum views.
And right there is your crucial link in the virtuous circle.... this encourages people to publish on In-Leo, quality content that is, which should help drive the ad revenue...
This all sounds good to me...
This is VERY early dayz, and although LEO is 50% higher than it was two weeks ago, possibly this is just the beginning....
That low percentage yield we have been getting on just staking LEO and curating, that's already higher now, and there's consistent buy pressure combined with incentives for, well, just holding LEO!!!
