Sorry, but it is still unclear to me, as an app developer looking for ideas, where should I post?
Where do merchants post requests for apps?
This link:

says to check out this thread:
http://ecommerce.shopify.com/c/shopify-apis-and-technology/t/what-kinds-of-apps-do-people-want-37865
Is this where I should look?
As an aside: It would be nice if there was a central place where ideas for apps were posted and merchants voted on them.
