Rereading the original post, I think it makes a really good point about being forgiving in a game played over the internet.

You never know whether a player might be a kid, or a great-grandparent (which is awesome btw), or might be new to gaming, or might have a disability, or might be experiencing crappy internet and lag, or might be sick, or might have unavoidable distractions like small children or parents or people knocking on the door at inopportune times.
