I'm still "wet behind the ears" as a "Hubber," but I think some balance is important. Putting out a good, short Hub is better than waiting too long. Of course, good, well-written and well-researched information is important as well. In my Hubs, I have been taking advantage of the "edit" option to add link and photos after the original post. While this may not always be ideal, sometimes I would tend to delay posting for too long while looking for the "perfect photo."
