Looks interesting. I like the modular approach the author seems to be taking. Keep the core small and extend with modules. However, there are some things I don't get about Nectar:
- it is meant to reduce the barrier to entry, but from what I've experienced, Laravel does a very good job at lowering it, - it seems like the framework doesn't come with Composer [1] support built in, which means you can't import all sorts of awesome packages out of the box, - other frameworks are modular, namely Laravel, Symfony, Silex and a lot of others: what does Nectar provide that these well established and battle tested frameworks don't?
I'm not trying to hit on Nectar, but I'm not sure I see its added value (yet).
