Yap, there is a Slack channel, someone posted a link a few days ago and it s not hard to find it. Still, I prefer Blog, Forum, anything static where crucial info s easier to find. Hunting down Factom staff over chat to ask them questions is not something I d like to do.
If you just consume (read) the slack channel so now and then, you will already be updated enough probably and there will likely be no need to 'hunt' them down for more questions. Others will do it for you. Now you are dependent on people who are on Slack to update you here. Don't think there is a point for them in doing so.
