Uses javascript syntax. yet another language, because it works. Only way

Can be scary. Nouvo uses only two blocks. Linkrewriter and Forms. Don't worry

Not sure who cocoon is for. Should be easier, or not. It's better to fail
early?
Command line is where you do the work. Don't expect buttons. No need to be a
commandline guru, but basic skills are required.

If you remember one thing, remember this: The hard part is the integration.
Many tools and libraries play a part in your application.
Need someone who can have an overall view of the whole app, for integration

Yes, if you are comfortable with the command line, if you take the time to
explore (the jungle). You need a long term vision for the complexity of cocoon
to pay off.
Suitable for heavy lifting, but can be used for simple projects, especially if
you are planning to take the project further in the future.
Invest in your skills, learn learn learn.

Cocoon is like the toolbox of a very rich man. Which tool do you need? Take
time to select the right tool. Otherwise you get lost. Don't be distracted by
what is all around you.
Full blown apps need a wide range of skills.
