- copy an id into a command prompt so I can find it in a log
- copy a method into a class so I can try to run it
- copy a serialized object to a buffer so I can diff it with something else
Now, we can argue about whether email is the most appropriate form for all of this, but that's a bit academic; I don't really control what other people do or send. Rather, let's look at one useful point:
This is all a lot easier if the email is plain text.
With plain text email, I don't get weird formatting issues. I don't accidentally grep for HTML. I copy-paste instead of copy-paste-delete. I can get you whatever information you need a whole lot faster.
So go ahead and send whatever you want in email. Just send it in plain text, please.
