Generally no.
A few larger companies do.

the more you walk, the lower your risk of death

So if I never stop walking I’ll never die!? Awesome!

I do. I watched it happen.

I did not. I didn’t have an iPhone to be able to get onto the settings with.

That’s the most iOS looking app I’ve ever seen on Android. Not a fan. Sorry

Notifications currently use Google services. It’s on the list to change. No idea when it’ll come.

Am I alone in not carding about about inter-series continuity?

Not a criticism. Just wondering if I’m the odd one?

Researchers have developed a novel vaccine that targets senescence-associated glycoprotein (SAGP) expressed in inflamed brain cells linked to Alzheimer’s disease. When tested in mice, the vaccine reduced amyloid deposits, decreased inflammatory biomarkers, and improved the animals’ awareness of their surroundings. This suggests the vaccine may lessen disease symptoms. The vaccine targets activated microglia cells which play a role in brain inflammation that can worsen cognitive decline. By removing toxic microglia, the vaccine may control inflammation and ultimately repair deficits suffered in Alzheimer’s disease. If successful in humans, the vaccine could be a major step forward in delaying or preventing the disease.

Lets try it this way. Would say your favourites things, include everything you like? Do you like some things that aren’t your favorite? Do you keep a list of everything you’ve ever liked? Would it be as big as the list of your favorite things?

Do you see the difference? It’s a mater of degree that separates them. They are not the same. That’s why they are two different words.

You are in a way. Just not only that.

Favourite and Bookmark are absolutely different things. They’re two different lists for you to use as you see fit.
Neither of them is a Like though. I’m not sure that fact is really debatable.

Mastodon doesn’t have Likes at all.

The star you’re referring to is Favorite. Those go into your Favorite list. So you can refer back to them more easily.

A unified API and a single login, are two separate things.

A single federated authentication could be a good idea. But the various federated services are different enough that they should have different APIs.

when I first log into Lemmy or Kbin, despite me having my settings set to show me only subscribed stuff by default, it totally ignores that setting (and what communities I’ve blocked) and just shows me the equivalent of /all

That sounds like a problem with the browser your using. Try clearing cache, going back to default settings. See if it happens in a private window, or different browser altogether.
