As a delegation option its a no-brainer, particularly while the devs aren't cutting the business in for a cut of the DEC.
We'll see how long that lasts. I got a daily payment (in DEC to steem-engine, from @splinterlands) around 10:30am my time, (8 hours ago) but I'd only just delegated so it only covered one round.
I'll see what the first full 24 hours pulls in.
