Leo is now pretty similar to ecency and peakd in the scope but with the tokenization of ads and a focus on short form by putting it as the default homepage. I am just really just excited that someone is thinking about how to keep money within the ecosystem without taking anything away from the content creators, and their ads+premium+subscriptions+liquidity pool system seems set up to do a great job of that.
The two best reasons to use leo is that you earn both leo and hive, and shorts are really really growing and have the potential to grow much more.
