On my new phone, I installed Twitter but never got around to put in my credentials. As that makes it impossible to see single tweets that are linked to from nostr as it always tries to force me to finish setting the app up instead of showing me content, I even **deleted** the Twitter app to get a better Twitter experience.
Is linking to Twitter a problem? I don't think so. If people get stuck browsing Twitter whenever they get exposed, let them. I suspect those who don't are more valuable to nostr anyway.
