You're right. But this article contains significant new information (SNI) about Excel, and spreadsheet topics are perennially interesting to HN readers, so this is the rare case where a quick follow-up article, and also the title change, probably makes sense. Usually it goes the other way of course:

https://hn.algolia.com/?query=follow-up%20by%3Adang&dateRang...

https://hn.algolia.com/?query=%22significant%20new%20informa...

Fair enough, makes sense, thanks. When I posted the comment it was the first comment on the thread (not sure if it's been merged or I'd had the page open a long time before posting) and we'd already had other threads with that leeway. Cheers for the clarification, I'd thought that might be the reason for the earlier ones.

Edit: just seen your other comment re merging, thanks.

The BBC has expanded on the Excel-related part and broken it out into a seperate article: https://www.bbc.co.uk/news/technology-54423988 Maybe it'd make more sense to link that one, if you're keeping the title?

Ok, changed to that from https://www.bbc.com/news/uk-54422505. Thanks!
