I don't believe someone didn't already thought that..
We update the site, blog, announcements, twitter, everything using HootSuite.
Site: because it's supporting Wordpress and soon Joomla and others.
Google+: Our page there on G+.
Facebook: Our page on facebook
Twitter: Our account there.
All automatically through hootsuite at once.
Should be usefull if we got a Hootsuite app from WHMCS Announcements too.Or / and network issues too. (Could be drop down selection like wordpress for categories to publish on hootsuite)
