I like Rails and see no need for a new basic web framework.
If we want to reinvent something, I'd say a new e-commerce framework is needed, Spree appears dead in the water and honestly, not that much better than Magento. Then again, with Magento 3's embrace of a REST API, finally we'll get to see a services approach.
But if someone wants to make a robust e-comm framework with Hanami, I'd be happy to evangelize that.
But I think everyone needs to just realize that stacks require massive numbers of developers to do well, and new ideas are going to rightly struggle to find traction against the behemoth.
