Do you really need Stacks?
Here is an interesting thread where an experienced RW user set out to demonstrate how a well presented site could be rattled together very quickly. It was in response to my contention that the core RW product, and the absence of innovation therein, is rapidly approaching junk status when considered as a stand-alone product (without its constellation of plugins).
Not sure if the 35 minutes in the oven demo site is still live or not - but it certainly gained some compliments - so perhaps some users don’t actually need Stacks.
