We're doing the platform approach. I don't think this was part of any grand calculation of where the technology wave is, just that it is the idea we have and it meshes w/our skillset.

The field does seem awfully crowded with social/mobile lightweight apps.

People prosper all over different parts of economic/tech cycles. My father was a developer (real estate kind, a regular "A Man In Full") in Atlanta, he used to always make all his bank during recessions when all the other developers were going broke. Conversely, during the fat times, he never did very well.

We (including Dad) were all aware of this pattern, but never could really figure out why things worked out that way.
