Thanks for the clarification (even for some rando on the internet), that makes a lot more sense... I think I'll implement a rule for myself where I won't comment on HN posts after first waking up anymore. Agreed that could totally happen!
'Put self into read only mode until after the first pint of coffee' is a policy that has significantly reduced the number of times I look back at a comment I've made somewhere and judge myself for its quality.
I mean, even fully caffeinated, I still manage to beclown myself on a semi-regular basis, but the 'semi' part is still a net win.
