Today I found out that Salesforce discontinues the Site.com Workbook.
Site.com Workbook Discontinued
We’re discontinuing the Site.com Workbook in Winter ’15. Other than the workbook, however, all other Salesforce Help and user assistance remains in place to support Site.com customers fully.
Therefore my question is: Is Salesforce discontinuing site.com?
In the spring release notes salesforce mentions that you can use "the newly expanded Community Builder to [do X] - with no need to go back to Site.com Studio." - (RN Spring15 p53)
Or there is another quote:
You still use Site.com Studio to drag and drop or delete page elements.
(RN Spring15 p57)
From my point of view it looks like salesforce wants to replace site.com Studio with Salesforce Community Designer.
