Facebook makes a big deal out of temporary pages to
aggregate account holders' notification that they've
somehow been spared of a natural disaster. We can opt in
to allow the FB to compile our relevant contact and
associates data to notify our friends and the world at
large.
In the spirit
of public health and disease prevention, the
site's directors could create a facility to allow us to opt in
for a short biopic of our recent locations (maybe since
01/01/2020) to show how many degrees of separation
there are between, say, me and reported cases of Covid-
19.
The matcher can use my name, location, etc. to compile
community transmission information. A user can also ask
for notifications, such as "You've moved from a low risk to a
medium risk group of friends" or "A friend of a friend has
checked into quarantine"
<lol> I like using the term "a friend of a friend" </lol>
