Hi Sedef,
Thanks for the question. The purpose of each week's assignment is to develop your thinking toward your final project. You can interpret that as you see fit.
However, I would say that John's lecture -- though talking about jQuery as the specific example -- was about how to get other people using your software.
So the question I would take away and apply to your weekly assignment from yesterday's lecture would be: How will I engage people and encourage them to use my software, and -- once engaged -- how can I turn those users into co-developers, helpful contributors, bug reporters, or positive world-of-mouth marketers.
Hope that helps a bit.
Phillip.
