I can't find the Wikipedia page for IOTA. I thought there used to be one. What happened to it? Did it get deleted? Why? Is there a place where more information on this can be found?
The IOTA page on Wikipedia was deleted because it wasn't a great Wikipedia article. It was poorly sourced, contained much information that wasn't in the sources given... They just decided to rewrite it from scratch because the article was so terrible. The only arguments in favour of keeping it seem to be about IOTA's notability. And IOTA is notable enough to have a Wikipedia article... just not that article.
The article has been deleted, but that doesn't mean that Wikipedia has no intention of there being an article about IOTA.
Here's the latest draft of the new article... which isn't much better to be honest. Why can't people just get together and write a decent Wikipedia article about IOTA?! This draft, being practically identical to the original, has been deleted. We'll have to wait a bit for an IOTA article.
More info here. This note seems to me to be the summary comment of why the page was "SALTed" (official term, not sure what that actually means) by user Jytdog:
