My conclusion is that HN's default search results are not very good for checking if something has already been submitted. Searching for "twitter" doesn't show any of these submissions, presumably because the default search shows only "popular" submissions.
HN should really implement something like stack exchange where it auto-searches for potential dupes

Searching for Twitter and Trump, and changing the search to "Date", shows all of them ... it's how I found them:

Having said which, the last of them is still on the Front Page.
