As the Salesforce Platform expands, the question arises - should Salesforce StackExchange also expand its scope? For example, ExactTarget is now the ExactTarget Marketing Cloud - should ExactTarget users feel free to ask questions here?
Personally, I think the answer should be 'yes'. There is, apparently, a large overlap in the user bases, and one bigger Q&A seems better than two smaller sites. The overlap means that a user here to ask an ExactTarget question might notice a 'classic' Salesforce question they can answer.
