Not sure if you were being snarky but having the ability to scroll doesn't fix a poorly structured article...

Things should be explained as they come, or have a linked explanation, or say things like "we'll explain what XYZ is later".

If an article is about a tool but I don't know what the tool is and the first paragraph doesn't explain it, am I really expected to skim the entire article in the hope that somewhere is hidden an explanation, and then go back and read from the top? That can't possibly be good story telling?
