Yes, but you see … a template is merely a starting point for you to take and develop for whatever theme you want – including changing colors, logos, moving around positions, etc. For some very good examples of this, check out some of the sites that have been nominated for “site of the month” over the last several months.
As JA develops themes, what they really NEED to do is not focus so much on particular subject matter, but FUNTIONALITY – i.e. social networking, web 2.0 interactivity, classifieds/auctions, video, more ecommerce, etc.
Otherwise, virtually any template can be molded for virtually any subject matter heme.
