Ask HN: how do you write Internet, with capital I or lowercase i?

I mostly use lowercase, after becoming aware of the debate and shift around 10 to 15 (I think) years ago.

I think the internet is still identifiable enough, and separable from the world as a unique thing, that it's not outlandish to capitalize it.

Eventually it will recede from uniqueness and capitalization. You would not write the Railroad today.

According to Wiktionary [1]: "Usage in reference to the global network is normally capitalised, reserving internet with a lower-case i for any other set of computer networks connected by internetworking. However, popular usage (e.g. BBC and Timesonline) increasingly spells it with a lower-case i."
