Thoughts.
If you're getting something of value out of it, I'd say go for it.
Weekly might be ambitious.
A member tried to do a community newsletter (monthly?). It died out after a couple because of lack of content.
The company I'm working for does a video newscast every 2 weeks.
Their format is always the same: housekeeping / important company updates, employee spotlight, then a sixty second update. In total it's about 5 minutes long.
It'd be great to get other people involved (Mumble, Hangout, Skype, etc.) for content. New members? New admins? Awesome OG board members?
