Its the weekend before the 4th of July, the independence day for USA - many employers give employees Monday and Tuesday off, creating a potential four day break during what is typically very good weather - that being said Twitter is presumably (still) an international company with people in all different holiday areas.
The "America is the default" is tiring. The US makes up ~ 5% of the population, and most of us do not default to American thinking.
I haven't generally used sentence-style queries wth any search engine since AskJeeves. Paitly because AskJeeves was terrible at finding what I was looking for, and partly because it almost always produces poor results on every other search engine I've known.
I just don't expect natural-language queries to work (yet). I've also watched too many people struggle to get "Ok Google, …" to return usable results; seems the majority of the time it fails or would have been faster to type out.
I still don't have a feel for Kagi. I used it occasionally when they had a free tier, but was always afraid my habit of submitting multiple revised queries to search engines would use up the free allotment. The current sample search for headphones was somewhat helpful recently, though "best x" is not a search pattern I tend to use, and even though I tend to search for 'phones with flatter response than most.
I have the base plan (1400 queries a month I believe) and regularly revise queries or put in things I should use something else for (e.g "current time UTC"). I'm yet to exceed the included query quantity.
