Anything that can be added on or made available, kept fresh, made useful, and does not distract the staff from the basics of providing solid uptime and secure servers...should be added.

My client base doesn't have a huge interest in templates; and their interest in add-on scripts is limited as well. They are definitely interested in information that teaches them to maximize their web space wisely - not just the concepts, but "do this, do that, make sure that this looks like this other thing". Many of them are small or single business people who know that a good web presence can help their business - but not all of them are sure how to define "good web presence". What's good for a design and hosting business isn't good for a wedding floral arrangement provider. They're busy concentrating on operating their businesses, paying their employees, watching and charting their own industry's trends. They don't always have the time to research web-related issues. They appreciate having it broken down for them by someone who realizes that they aren't idiots and they aren't even necessarily ignorant - but they *are* extremely busy.
