I discovered a new blogger today. This post was pointed out to me by another IBMer:

There are three main benefits adoption of one platform over another can offer a developer. These benefits are captured in the following "laws" of platform adoption  

1. Developers adopt a platform when it offers differentiation from competitors: In competitive software markets, building an application that stands out from the crowd is important. Platforms or technologies that enable developers to provide features that are unique to the application, even just temporarily, are thus valuable to developers in such markets. Typically, if these features are truly valuable to end users this leads to a "keeping up with the Joneses" effect where the majority applications in that space eventually adopt this platform. Recent examples of this include Flash video, AJAX and the Flickr API.

Apparently, there are a few issues with the IDS install on Mac, Carlton Doe has put out a document to help with any problems you might find.

You can get the document here.
