From someone who has never even ventured into object-oriented programming: Why Ada? From the Wikipedia level overview, it doesn't seem like it offers much over Java or C# (remember, I haven't touched any of the three). It does look to be quite a bit more readable, which I like, but I still would have a hard time justifying its use over languages that have endless libraries and strong communities with similar features/paradigms. I'm sincere about the question, and I hope this doesn't come off as snarky.
