Now, a simple question is why would I want to use this over materializecss.com? I saw this from the FAQ:
>That said, the large, diverse number of implementations available are often quite liberal with their interpretation of the spec (not their fault!) and their opinions don’t always reflect what the Material Design team would consider ‘correct’.
It doesn't specifically point out what these guys are doing wrong and I personally can't see much that is being done differently. Are there any specific examples you can point me toward?
Why make a completely new project rather than working with the communities out there? If the spec is too liberal it should be updated and issues posted under these projects, so these projects can properly follow the spec, unless they specifically choose to deviate from it.
Any idea when we can expect these to make it to polymer 1.0. Basic components like dropdowns/cards are missing atm .
