i'm giving you the benefit of the doubt since you generally style yourself as voice of reason on hn.
that being said you're not addressing my challenge, that this thing
>That's what blogs are for.
isn't actually the case.
take for example your characterization of this kind of miscellany
>shitty first drafts of things
can you name another medium/form/forum where authors publish "shitty first drafts"? why is blogging different? because it is ephemeral and has 0 mass by virtue of being digital?
on the contrary take something like twitter, for example, and compare its relative weight, ephemerality, inchoateness to your blog posts; tweets are very much fair game for all any kind of engagement.
