Anecdata/opinion from me: Discord's infinite chat history and search [note 1] is a winning feature for me, and it's frustrating for me that other services I still use don't have that. For example, FB's Messenger app still doesn't have message search, even though the desktop version does. Why?!
[Note 1] However, Discord's message search seems to be quite finicky when it comes to searching links. For example, if someone posts a link with "www.twitter.com/user", it wouldn't show up with a "twitter.com/user" search, but it would show up for "twitter.com" or "www.twitter.com/user". Room for improvement.
