I was thinking that one could spend an extra b5 to have a bulletin they're posting to be pushed to our feeds, that is, the "Recent Activity" feed on our site, Twitter, Facebook, and RSS, just in case someone wants to spread their message further. To take Twitter into consideration, perhaps there could be an additional text field to specify an alternate title, in case the bulletin's title won't fit on the Tweet.

my instinct is it should be more expensive than b5. maybe twice as much as usual?

yeah, as someone who has the botb twitter account sending me texts so i know when there's an ohb, i'd say definitely more than 5b.

This idea should be coupled with Level requirements and higher boon cost (as previously stated) to prevent from trolls sending out "hello, i like penis tehehehe ^^" just because its so damn fun.

Other than that, I think it's an idea worth thinking about.
