That being said, any other services could be shut down via an aqui-hire, or other reasons. Maybe this is the prevailing problem of small time developers like myself, and there's no other way around it apart from getting your idea bootstrapped with these services, and hopefully by the time any of those services gets shut down (if ever), you'll have a migration / backup plan of some sort.
I remember some of my friends saying they received more in grants and bursaries than what I made in that 4 month period alone (with no effort, to boot!), and that slightly discouraged me a bit, but one needs to remember this is an investment that will pay off in the next few years.
That being said, I was enrolled in a software engineering program, but most of my friends have found work in EE as well.
