The question we were addressing is where your state should live. @boubiyeah questioned the wisdom of storing all component state (e.g., the current position of a cursor) in a global atom. You responded that "[l]ocal component state is new two-way data binding." Yet yesterday you advised that component local state should live outside of the global atom.

Maybe it wasn't disingenous, as perhaps you've simply changed your mind. But then you should make clear that your opinion today is different from what you advised yesterday, as it bears on the credibility of your current advice.

Hm...my response was the exact opposite of that. Maybe I need to rephrase?

In bullet points:

1. Yesterday someone presented a case where they needed to interact with a DOM API that used local state.

2. I didn't think it would be worth the trouble to wrap that API.

3. That is not an endorsement of local component state.

Hopefully that clears things up. :)

Don't feed the troll. While @ablesearcher's obviously part of the Elm community, he's using a throwaway account to vomit angry rubish on HN.

When did evidence-backed criticism become synonymous with trolling? Also, which statement exactly was angry? (Let alone rubbish? Or, gasp, vomit?)

It seems you want all Elm news to be positive Elm news. So does the language's author. In fact, when addressing the announcement re: Hacker news, he wrote this:

"Just an FYI, if you go to a HN post via direct link and vote on it, those votes either do not count or are used as demerits because it indicates that people are trying to artificially boost things. I guess getting a kickstarter to the top of HN can be worth a lot of money, so they try to protect against voting rings."

Civility is important. But so is the honest, unfettered exchange of ideas.

[rlander]

Well, for starters, use your real name, like the rest of us, not a throwaway account.

I guess if your issues were legitimate, we'd see a post on the mailing list, not an open attack on Richard's credibility.

For the record, this is evidence-backed criticism:

Yours is just trolling.

[ablesearcher]

Let's proceed in reverse order:

1. You don't get to define evidence-backed criticism to be only the criticism that you appreciate.

2. I didn't "attack" Richard. I pointed out an inconsistency with other recent statements that he has made, that bear on the credibility of his current advice.

3. I'm not sure how my identity is relevant to my ideas. But the reason I don't post under my own name has to do with requirements of my job. (I'm not a programmer by trade.) I can't have social media accounts. In any event, this isn't a throwaway account. These are, in fact, my first posts to HN.

Not everyone disagreeing is a troll.

[nwienert]

So basically you think it's ok to use local state, but only for DOM related stuff?

[rtfeldman]

Nope, just that the effort required to wrap something in a nicer architecture sometimes outweighs the benefits you'd get from the upgrade. This was one of those cases.
