Quality versus Commercial

Just recently I have been faced by the dilemma of whether to go overtly commercial in the pursuit of advertisers or build something with a bit more quality and integrity. These decision are always difficult and in the end any decision will only be a contributing factor to the final decision. Of course Cash is king but quality lasts. It is a very easy to match your product to an individually group of customers. Problem is will it be of any interest to anyone else. On the other hand having your own niche market is also great.
