Questions are great and what I always try to do when I am leaving a comment on other blogs.
If you get a question don't be in a hurry to answer it, take a bit of time think about a response, jot down an answer on paper or wherever you put your notes, structure it out like a post and then respond.
This way you can make the most of the comment left you by adding in more information relevant to the post.
There are numerous ways to respond to questions to make the most of this resource.
The best way I have found is to try and incorporate a conversation. if you can add a question back into the comment when someone leaves you a question. That way the back and fro replies are all great for extra content on the post and work wonders on Google.
Here is such a conversation I had going on one of my posts.
To be fair you do need a willing user (a BIG thank you to Colm for this one) to get such a conversation going and if you can get three or more individuals to join in so much the better. As you can see from the one above I was able to provide extra use of keywords and put in a link or two. You can see the full post here.

Lol, glad you did cos all 3 comments for WA reviews which I made today, I was afraid to use my Bootcamp website and used my niche website instead. That clearly shows how confusion can arise from all the recent discussions going on about how to/not to leave comments.
