So, coming up a bit from the discussion in the thread something did cross my mind. There's certainly a line of "whatever works best for your plot" that is a valid response, BUT...
I was wondering if there was any official ideas on how interstellar communication work and how fast a story from one colony might make it back to other colonies/news media outlets/etc. Having seen a couple different things in different settings (none of which need to dictate anything here, obviously), but they all lend a different direction and feel to things as part of the larger setting as a whole.
The real world style option: "It's bound by the speed of light and bandwidth is super narrow so anything broadcast back and forth will be laggy and minimal."
The Forever War style option (which is an extension of the real world option, really): "It's bound by the speed of light, but we shoot repeater drones (which can be really small/unmanned/etc.) through [space travel shortcut mechanism] at relativistic speeds which help cut down on the amount of lag in trying to transmit chunks of information (but it still may be significantly delayed reaching some places)."
The Ender-verse/Hyperion cantos style option: "The [magic internet/data/broadcast analogue] works instantly across any distance (but may have restrictions on access or bandwidth)."
In thinking about the concept of the transit gates and the safest travel option being a "coordinated on both ends" scenario, though, it seems like it would need to be something along the lines of the last option.
