Why the DailyUI challenge sucks?

The DailyUI challenge is a 100 days based daily challenge activity in which people who want to enhance their UI design skills have to create the design based on any given topic for that day but without any context or background. To create a UI there are many things involved such as layout, typography, information architecture, color system, user flow, accessibility and to focus on all of these in one day is a mammoth task for any participant.
