Flash and Web-Based Applications

Nielsen's alertbox talks about web-based applications using Flash on the front end. I recently talked to Molly, a new aquaintence in NYC, about how her organization was using Flash to put a front end on a project management db. Sounded like an interesting idea, only because I haven't seen a project/client contact type db done in Flash before.

    In usability tests of 46 Flash applications, we identified several basic issues related to Web-based functionality's ephemeral nature. Some findings restate old truths about GUIs; others reflect the Net's new status as nexus of the user experience.
To digress a bit, the Flash based apps I've thought work well lately are just for fun, e.g. this Bush speech generator, tuning the world. I've come across some design sites that have all flash interfaces with databases, but at the time felt turned off by them. I'm coming around, though. For me, a Flash interface for customizing a product design, like timbuk2 bags is excellent. But what are good examples of content-heavy sites that use Flash, like Molly is talking about? Are there any portal-type sites using Flash?
