I'm still starting out, but I'm trying to average 2 hubs a day for the first month. Day 10, and I'm still keeping up. I have 21 hubs published, and about 6-7 started drafts. I don't know how long I can keep up with this pace, but ideally, I would like to stick with this rhythm until I reach 100 hubs, and then maybe tone down to 1 a day. We'll see!
