Disclaimer: I don't want to start any fight against Google Fanboys. I'm just asking because I didn't find a direct answer to my question and maybe someone who already started working with it (or any googledev) can give advice.
Google recently announced Material Design Lite 1.0 and the project has been starred over 9k times on Github in a few days. I read some posts [1, 2] comparing MDL vs Twitter Bootstrap and I don't understand why anyone outside Google's headquarters should consider start working with it.
As they said:
“We challenged ourselves to create a visual language for our users that synthesizes the classic principles of good design with the innovation and possibility of technology and science.” – Google Material Design Introduction
So, why are they releasing MDL? I just don't see the point on wasting time on learning/switching to a new frontend framework which offers much less than the existing ones. MDL looks different, modern and has nicer transitions. That's all? Is there any technical advantage?
