I 'vouched' for your comment because the actual content doesn't seem out of place to me. My guess is that users flagged it solely because it was all lowercase, and informal (the last part, that is). HN has Reddit-anxiety: people here want to avoid comments that are too casual, jokey, meme-y, 'meta', etc. Anyhow, welcome!
