I would ease it out there for my users, and let them see continuing development. Google and user will both like that. Depending upon the content, establish or expand site sections and then set the faucet to drip, drip, drip. Customers are more likely to tell potential customers if they see that you are developing more and more every time they buy.
You may get some strongly differing views on this, but I like to have a 'library' of content in reserve. Also handy if a competitor suddenly starts making a stronger effort themselves or is actually innovative. We have a 'response' and counter measures and can mass email my customer database if need be. We use very little email marketing and save it for when we really have/need something to say. Our repeat business is strong enough on most sites that there is more downside to spam than potential. Infrequent follow-up is business. Consant follow-up is spam, IMO.
I recently bought very well known (and not inexpensive) software for CD burning. They have been spamming me weekly ever since - as do many other businesses. I may do more business with them because of the product, but I will speak ill of them because of the company - be certain of that.
