Why? Because I’m a curious fool, that’s why. 
I mean, it was interesting, very much so. So I clicked on it. I’m not going to duck my responsibility - it was me.
But I did stop myself for posting. In fact, I actually thought to myself, “mmmmmm… Nah.” The thread made me feel oogy, that’s all.
Now, Esprix, don’t you think you’re being a tad alarmist here? Let’s assume that the powers that be have some kind of plan for “raising the tone” of the board. And let’s further assume - just hypothetically - that they did plan on making some kind of announcement to that effect. When they do so, I think it’s also safe to assume that they’ll do it in the same manner as Tuba’s Pit Rules thread - in other words, ask us all for input.
Ok, you may think. Well if they were going to do that, why didn’t they wait until after creating that thread before closing Scylla’s? And you might also think, “Well, why did Tuba have to be so harsh about it?”
Both would be very good questions, and I’m not disputing their validity at all. My thinking is that Tuba and others had been kicking the idea around - in a general sense - and that they did plan on announcing something in the near future. Then this thread popped up that pretty much fell under what they had been considering - but they hadn’t told us yet. So Tuba, being human, basically did a “uh-uh, no way” kind of post. Abrupt? Yeah. Brusque? Yeah. Harsh? Sure. Won’t argue with any of these assessments, really.
Of course, this all could be wrong. Perhaps there was a different reason for closing the thread - perhaps a fuller explanation is in order.
But personally, I fail to see how it’s the end of the board if that particular thread is closed. You can connect the dots all you want, but it’s all speculation.
