At this time, only the approved representatives of a company can post company status updates. Since at this time you cannot tweet company updates or share them with groups, I share it from my personal profile with groups that I think may find value. My personal updates can be tweeted.
Alternatively, any member of a group can initiate a discussion in a group. Discussion, similar to these forums, are possible in a group that are not available with a company status update.
Job postings are available on both company pages and groups.
An annual conference is a great way to start a group, that could be kept active throughout the year.
