Exactly what I said (except, I didn't mention why the chats stopped), lol.
Also, the IRC chats have existed in the past before that last attempt, as well, but they eventually dissolved due to lack of interest. They always start out alright, fully backed by numerous members...then the numbers start dwindling, until finally there's only a few people left, then none.
But yeah, like Nikki said, the Justin Miller chats have largely taken over the need for a video/text based chat.
And it's actually better that they're scheduled like they are, instead of any time (like an IRC chat would be), because then that coordinates people from different time zones to be on at the same time (which is another problem we had with the IRC chats).
Overall, the Justin Miller chats are plenty good enough, as far as real time chatting is concerned. I mean, you can try to make another IRC if you guys really want, but when history repeats itself I'll be sure to say "I told you so."
