I've looked at it, I'm just not invested in much deli-wise other than my own initiatives, But @therealwolf, @smartsteem was as I recall, among the BEST. https://smartsteem.com/
1000 SP deli returns .342 Steem PER DAY and 10,000 SP returns 3.42 Steem per day!
Pretty darn good, IMO! Not as good as Maxey said above, but worthy of a look in these markets @rok-sivante :) I also listed what a simple delegation would do, not vote selling...
