I have been thinking about the same issue too, a lot, but from a learner's perspective, since I am finding it daunting to come with examples and problems that match my progress rate, I am reading off this huge technical book and it scarcely has any examples but it is rewarding, I use my imagination to come with programming scenarios and start acting accordingly, of course, sometimes I become partial and skip some of the areas I need to focus on, which is not the best thing to do, so this is like a great initiative. Best of Luck
