For the long haul.

“Given that times are tight, longevity is so important in entertainment. I still play The Sims 2 four years later. In regards to comics, a very important question comes up: can this book entertain me after it has been read? Has an online community developed around the book? Can I have a lively discussion about this book with others? Does the creator provide random content in installments during ‘down time’? (Sketches? Sneak peaks? Snippets of the creative process?)”

These are difficult questions for a creator. You can’t simpy fabricate a community. One must develop naturally. However, actively interacting with fans can help.
