Mostly a captive market of Microsoft-oriented devs with invested skills in C#/VB, and an ability to push out a client install package through Windows update. Having developed against both, I found Silverlight development much easier than Flash development. It makes the most sense for enterprise/corporate/internal applications, where end-client availability is much more controlled. But outside the firewall, Flash is certainly good enough.
