+2.
One thing I think would be incredibly useful is if we got in the habit
of briefly explaining our methods if we can't include a code to show
it explicitly. If a sequence can be easily computed using the
standard tricks (brute force, sieves, etc.), then that's fine, but
there are many sequences where I haven't the foggiest idea how a bound
or term was found and it seems completely magical. In some cases even
a few words would make all the difference. I'm as bad about this as
anyone although I've been trying to improve (e.g.
http://oeis.org/A177875).
This would not only be good for teaching purposes but could serve as
another sanity check, if someone can look at an argument and say
"Wait, that doesn't work.."
