I find it amusing that even when you're on the MDN Blog URL (https://developer.mozilla.org/en-US/blog/), it still shows you a banner on the top that says "Discover the latest web development insights on our new MDN Blog", which links to the exact same page. :)
I'm excited to see the articles they produce.
I was a bit disapointed to see their RSS feed doesn't let you read the posts in your reader of choice.
Just some generic "click here to read more" descriptions and massive images.
I get that they're wanting to to sponsored stuff and for that they need stats and what have you, but I expected a bit better.
MDN has the advantage of being more accessible (!mdn bang on DuckDuckGo, Dash docsets) but I prefer O'Reilly's Pocket References, although they may be a tad out of date.
Hopefully this can help fill the void left by CSS-Tricks.
Perhaps the intro blog post should be the one linked: https://developer.mozilla.org/en-US/blog/welcome-to-the-MDN-...
Interesting that they'll have sponsored posts.
