I'm trying to make a game for steemit and it would be really useful if I could put text information on a block that wasn't a blog post or comment. Is this possible?

Also, is there anyway to get notified by the blockchain when someone replies to a post? Currently, I'm simply scanning the blockchain every 3 seconds to see if anything has changed. It seems very wasteful compared to a listener.

AppBase enables many components of the Steem blockchain to become modular by creating additional non-consensus blockchains as dedicated plugins.

I really wish I knew exactly what that meant. Sounds awesome though :D
