(replying to @alexthepres and @compositor)
if "tack on" isn't a typo of "take on": converting twitter into a fedi instance would have been neat, and is definitely something I would want if I was the owner (well, that and doing something about the RAMPANT bigotry)
if you meant "take on": I think I read someone say they're trying to turn it into a quote-unquote "everything app" ? (even banking???? I wouldn't even trust them with a nickel.)
...isn't a web browser already an "everything app" ?
