@navitux my problem is that I've seen almost nothing (except for Sita, which I mentioned) that's really good made with it. Either good artists aren't using it for serious work, or they're being really quiet about it. The former would be a bad sign: suggests poor alignment with user needs. The latter is improbable: awesome users tend to evangelize the tools that help them be awesome.
@2ck I don't know but I have seen animation works and good tutos with that, it's just open alternatives, even exists other online suitable options, but what is available, once the project requires it you can change the tools
