I hope there's a distinction between disseminating information and being an armchair general.
If I notice something on the map I'll post a quick notice for those that might not be looking at the map, even if I'm in the middle of a mission and can't make it myself. Something like "Looks like NOE inbound xxx" or "yyy is getting hammered" or "CV sector xx.xx.x". I'll post that information once. If anyone acts on it great, if not, oh well. I don't consider that being an armchair general. I'm not asking anyone to do anything; just letting them know in case they are interested and I'm not whining about it if they aren't.
Oh... I forgot, I do sometimes also post "Could use a little help at xxx". Again I post once. If someone shows up (most of the time) great, if not then it's me against whatever I thought I needed help with.
