I don't seek I *care*. 'platform' is a marketing ideal that does not exist in real-life. 'Platform' is what you would get if only you could rewrite everything at once in a single homogeneous whole. 'Platform'-oriented people battle their own partners to prevent them from getting useful stuff done now and insist they should wait for the pure 'platform' solution that will materialize someday (just like SUN fought tooth and nail to get everyone to use the universally hated swing, and ended up with no gui presence at all)
Real-life successful products are mongrels that accept the holy platform is an ideal that won't be attained, and make it easy to reuse code written for previous platform endeavours.
