Many online communities find it useful to have one or a few centralized social media accounts (eg https://twitter.com/#!/Wikipedia and http://identi.ca/Wikipedia).
These are often shared among a few people who can post, with passwords shared in some informal way. Could be useful to have a frontend that uses the wiki's user accounts & groups system to moderate access to post out through such things.
This avoids forcing people to switch accounts online or share passwords insecurely, and would allow things like on-wiki blocking to take effect.
