And the header links back to the blog, not the main website.

And the older versions looked like every website of their era too. Back in 2011 with the "floaty" design (as I can't seem to figure out the real design term) and in 2015 with the material 1.0 design. That's normal!

That's how websites usually work especially when they are mostly portals for the actual product, not the product itself ;).

I really like the new design, much better than the sort of material 1.0 flatness it used to have.
