It's been about a while Polymer version 2 is available out there, but
- few people talk about it
- few developers write about it in their blogs
- few developers share their workflow and their experiences
Polymer Project is powered by Google, and the team seems have impeccable philosophy behind it.
Beside lack of browser support, Polyfills are doing the job still fine.
By the way, It seems people don't prefer to switch on it and work on it although Web components is an standard of the web.
There's a big why for me, there should be an explanation.
This is I think is related to Stackoverflow However I know many wouldn't like this kind of questions.
