Well, I think what would happen today is that those apps will be buried in the noise of Facebook app streams and will be less successful (in expectation at least) than their 2007 counterparts (unless the course comes with an equivalent focus on marketing efforts for such apps). There are just so many more commercial apps with heavy marketing resources behind it, that the average student app would unfortunately have a much tougher time getting the attention of eyeballs.

That being said, I have enrolled :)
