Are people having problems with sharing their projects with clients or something?

More on topic/ (original comment):
I'll say something since one of the worst things is putting a ton of work into something and getting crickets.
There's clearly a lot of effort put into this. Really like things like clearly outlining a scenario, and external links. Not enough people remember that the web is supposed to be interconnected and build on other resources. I especially like that it's not just one site, but a variety of sources like videos as well as articles.
But I don't understand why this is presented as a series of "challenges". It works much better as a reference that I can use to stay up-to-date with the industry. I am not actually going to sit down and do "exercises" to make mock survey questions. That kind of stuff is useless without context of a real job with real parameters, real requirements, real people you can ask to clarify their goals.
The website as a whole is an excellent resource for ui/ux. Definitely bookmarking. And I hope you continue to push out good content like this because it'll make a central authority in a pretty big field.
Also, I am really curious what the other countries were in your survey. Because that was the largest group of people. Is it mostly from asia or something?
