I hope your telemetry is APRS compatible so that it can also be
distributed by the global APRS-IS system already in place. If nothing
else, it only takes a leading ">" byte to make it "aprs compatible".

Yes, Emails automatically work for anything that can digipeat because
APRS-IS stations automatically link those packets into the APRS-IS where
they are picked-up by existing APRS-to-Email engines.
In this case then, the ability to send a tweet via APRS is simply an
application that monitors the APRS-IS for any APRS packets that looks like
they contain a "tweet". If we do not already have such an engine
somewhere in the world, then we do surely need one. And so your request
is a good one. And this is basically what PA3GUO is suggesting below..

automatically forwarded to the internet already.

Celsius. The tweet could be: "Hi this is CAPE-2 in space, I feel cold
(12C) and my battery is good (10.5V)".
