Unlike you, perhaps, I do not READ code or output in an e-mail -- I immediately (if it looks vaguely interesting) paste it into Mathematica and run it. Frequently I find the code doesn't do what the post says it does, and even more often, I want to modify it and see what happens THEN, so this seems a useful strategy. That frequently means, of course, that I've pasted output cells as well as input, so I spend a few seconds deleting them. But even if I don't delete them, it usually makes no difference. I usually don't paste interspersed textual comments, but sometimes I do, and I have to delete those too. Generally they're not in-line with the code (they certainly shouldn't be!), so it's not hard to tell what's what. (* I'm not talking about Mathematica comments, although I never use those, either. Until now. *) Deleting In[..] and Out[..] "crap" (as I call it) is slightly more tedious... it's usually in-line, and deleting it is mandatory, since the code won't run while they are present. It's true that posts without In and Out may (at times) leave a reader wondering which lines are input and which are output (which to delete under my strategy described above)... but evaluating them one at a time (or all at once) will generally make it clear in seconds. Anyway, I think an experienced reader can tell input from output most of the time just by looking. As for knowing in what order you've evaluated things... I evaluate from the top down. Strange, I know, but that's just me! If I change anything I reevaluate from there down, and if in doubt, I evaluate everything (top-down) to that point. One line that, in fact, I often evaluate out of order is: Quit but then I delete that cell. Over time I've developed second-nature habits to support the overall strategy. As you have done for your own strategy, of course. Any number of things can cause me to delete an e-mail precipitously... and a dozen In/Out instances is frequently one of them. Nobody out there really needs my help, of course, so... to each his own!
