Don't fret, not all my hubs have comments in them too. As long as they are reading your hubs, the comments will come. You have to let people know you and your style of writing. This is a good way, by asking this question. The other thing is going to forums. Go to newbie section and ask this section... they are very helpful in forums and they will steer you the correct way. I didn't do this when I first joined.. like you, I just started hitting the keyboard. Well, I'll go now and read your hubs. Best wishes.
Have a nice day,
