Edge has an Internet Explorer mode, which is just running IE with Edge wrapped around it. They’re making it harder and harder to use, but they know there are big spenders that will just stop updating if they ever try to take away IE completely. Source: I work in Healthcare IT.
+1 for Cribsheet. She’s a statistician, it’s not so much “this is how to do it” as “here’s a few things people try and data about how effective they are.” It’s a great way to give useful information and encourage parents to make their own decisions about how to raise their child. When my wife was pregnant we read it together and it started a lot of good conversations.
