A
post intended for a large audience yet
posted on a single person's
wall to appear more genuine. Since proxy wallposts are visible through homepage feeds, one can advertise a trait of oneself that would be construed as bragging if in the form of a status.
Suppose you want to advertise to your
friends that you are caring and social. This is impossible to brag about, so instead just find your friend who shares the most mutual
friends and write this gem of a proxy wallpost:
"We had such a great
time last week! I miss you so much <3"
Soon, everyone you know will see it in their feed. And, unlike a status, no one will call you on it for fear of you playing the None Of Your Business card.
