What do you think about the timing right now for putting together apps for other mobile platforms, like Android? I am thinking of getting into it, since iPhone seems crowded.
Well, earlier is always better for jumping on a bandwagon... I think the real question is how well Android or Palm's new OS will do compared to the iPhone. In my mind there's a strong parallel between Facebook's platform/Open Social and iPhone/Android. Facebook platform/iPhone apps are centralized, consistent, sexy, first to market, and get all the media attention. Open Social came later, required more effort (more fragmentation), and got far less media attention (I haven't followed it closely, so I don't actually know how successful OpenSocial apps have been compared to Facebook, but my guess is much less successful, despite OpenSocial's larger potential user base). So I'm curious to see if the Open Social/Android parallel will hold.
So if you get into Android now and it fizzles out, then you've wasted some time and effort. If you wait and it turns out to be as successful as the iPhone, then at that point it'll also be crowded. I wish I could predict the future :p
