In defense of chat, it's generally a great place. It's just that on occasion one or more person will forget the rules or have a pissey day and it reflects in their interactions with the group. I am far from innocent on this front.
A lot of the time mods are actively present. Today that wasn't the case. For over an hour I also checked the Forum (about once every 20 mins so I could have missed one) and no mods were logged on. It was just bad luck.
Again, /ignore would fix a lot of minor problems. I suspect there are many who would love to use it with me, at times or even permanently.
Which brings me to: If we do progress to having /ignore, I honestly feel it should be time limited, like a "cool-down" period kind of thing. The emotions, topics and waves of hard science and insanity come hard and fast in chat, so a time limitation would allow the ignored person's voice to be heard again - maybe they have chilled and are now apologizing or back to being on topic and civil.
