Topics and Collections work hand-in-hand but are definitely different.
For starters, Topics find the content you are looking for. Within Topics, you dictate what you want UpContent to crawl the web for, and it'll produce results.
Collections, however, are what store your chosen content and act as a staging area.
Within UpContent, Topics, you send content to Collections! Collections are the way you reach out to your audience!
