Most important messages
go straight to your inbox on Facebook. But there's a second class of
messages, including potential spam and notes from people not in your
network, that the site's algorithms deem "less relevant."
These unlucky missives
are dropped in the little-known "Other" folder, where they will often
spend the remainder of their digital existence unseen, unread and
unloved.
"Several commentators and
researchers have noted that imposing a financial cost on the sender may
be the most effective way to discourage unwanted messages and
facilitate delivery of messages that are relevant and useful," says the
post.
The "inbox delivery test"
will be available only to select people using Facebook in the U.S. for
now. Companies won't have access to the feature at this time, and people
are limited to one paid outgoing message a week to minimize abuse.
