I find that if I go back and tweak a few aspects of the hub, that hub will get a few hits for the day shortly after. Now, this isn't going to guarantee any comments, but should get you a few page views. Hopefully in turn those that read will give some type of feedback though.
Finding the right followers will also help. If you write and article on fishing and then find fellow hubbers who have written fishing articles, then they tend to stop by and leave comments and reviews. This would be a great way to get started by the way. Good Luck!
