And with respect to the gazillion-dollar price tag comment of my co-presenter, he should know better – he knows who we use to develop our apps .

More to the point, however, I’ve seen few instances where development costs should be prohibitive even for smaller companies – the real cost as I see it is in the upfront research and strategy (to determine if it even makes sense), and then ensuring they remain relevant and sustainable over time.  

Two things — first, grammar/debate geek Bob says that it didn’t "beg the question" — begging the question is when you make a proposition that uses itself to prove itself. It may have RAISED the question, but it didn’t beg it.

Second, you forgot the most important thing we learned — that you guys charge a hundred billion zillion dollars to build a simple Facebook app.
