I don't think this is entirely true, I know it has had problems, but there was a time it was better. Without trying to going into a lot of the technical details that will bore most people into why it has been bad then better and worse again, there has been some back and forth on the hosting and how the backend chat server has been working. Right now we are on a hosted version of Babble. Just installed a release today that I am told should clear some of these issues up.
If it doesn't, I will have to return to a self hosted version where I can control resources allocated to it. It is not a quick thing to set that server up, so if I end up going that route, it will have to wait until I can find the cycles to do it.
