In the lead up, and subsequently delayed, Model X reveal last night, TMC was repeatedly overloaded. The most crowded threads had as many as 4-5 times the number of guests as the numbers of members present. It was pretty annoying (and several others echoed this sentiment) that those of us who have at least taken the time to register with the site were unable to communicate with each other during this, let's say, mildly stressful time - is the TM stream malfunctioning? Is my system malfunctioning? Who should I follow on periscope? etc, etc. Would it not be prudent to consider locking threads to members only once the number of guests reaches critical mass?
