I certainly disagree that the implication you read into it was there. I read the statement as a friendly bit of banter, not an implied accusation of ignorance.
Only on HN could someone implement networking from scratch, only to be dismissed by friendly banter in the comments implying they've no idea what they're doing, only for that to be misinterpreted as actual criticism, only for an analysis to be done on this comment thread :-) only for dang to appear and ask us to stop being so meta. Also, in TFA the font is 3 pixels too far to the left and it made it literally unreadable for me
