Seeing as normal users can also enter through registration I'd imagine it more like a portal to the snafu world. And with the situation in the comic there should be a tense argument about whether to seal it off or not. An argument where one side hopes that "somebody will come through and help us" while the other one goes "Nobody will come. We're on our own".
Then that becomes a perfect setup to get Nobody back into the comic. And there was much rejoicing.
