Quality of content would always matter. However, few observations from my side are:
a. We do not always find what we are looking for.
b. Even if we find some reference or course on what we are looking for, it may not be structured (as Adrian also mentioned) the way we would prefer.
c. Even if the course is how we would prefer it to be, it may not exactly match our learning aptitude. So we move on to another course.
Like-wise, there could be multiple reasons why new projects would still be relevant in the online educational sector.
But, I do agree that all these content can be overwhelming sometimes, and disconnnecting once in a while from the virtual set-up provides much needed relief.
