Strangely enough I originally posted this to HN as a threadreader link, but it looks like the mods switched it to the original thread on Twitter. I can't remember ever seeing that before. Is this a new stance that HN now frowns upon threading apps?

A number of URL remappings occur automatically, and Threadreader conversions may be amongst these. OTOH, Reddit links seem to be automatically rewritten to old.reddit.com.

I've suggested YC consider running its own Nitter node for that system's UI/UX advantages.

It's not a new stance, HN has always pushed for linking the original source unless the referring source adds something meaningful.

I'd personally feel thread unrolling is a meaningful addition, but I don't think that's ever been the mod's POV

this should have been a blog post. I absolutely can not stand threadreader because there's something about how people use it that rubs me the wrong way.

It does not help solve the fundamental problem (this should be a blog post not a series of Tweets).
