social media sources of amateur astronomy news; are there any?

Are there any Twitter or other social media accounts worth following
for one interested in: 1) rapid notification of new comet discoveries
or outbursts of known objects; 2) rapid notification of new
Earth-approaching minor planet discoveries; 3) rapid notification of
new extragalactic supernovae discoveries; 4) news pertaining to
forthcoming meteor showers?

For 1) above, I previously used the website of the Central Bureau for
Astronomical Telegrams, but it seems that many of that website's
pages are no longer updated with any regularity. For 2) I sometimes
check the Minor Planet Center's Near-Earth Object Confirmation page
but it would be preferable to have the 25-30th magnitude objects
filtered out. For 4) I previously referred to the meteorobs mailing
list archives website, but that site seems to have suffered an
untimely demise a couple of years ago.

I am interested in intermediate to advanced amateur-level information
(something beyond which Astronomy Magazine of Sky & Telescope would
provide).

Snews is one such source for coordinating supernova reports.

Although they encourage amateurs to feed in their observations via Sky &
Telescope's AstroAlerts portal:

There are other pro-am collaborations on cataclysmic variable stars and
a few other targets of interest prone to transient phenomena. Impacts on
Jupiter being another which amateurs can easily contribute to if they
happen to capture an event occurring. Today there is near continuous
amateur video capture of the planets disk when it is visible.

Links from this site include some other am-pro coordinated programs:
