I’m going to throw my vote (which counts double, now that Obama’s in office :D) behind “Stuff I Must Share” unless someone comes up with a better phrase connoting miscellany.
If people are still seeking an alternative, I’ll throw out “Around the Water Cooler.”
I like “Stuff I must share”. It retains a connection to the old name, important for old sentimentalists like me, while removing the problematic “mundane pointless”.
It’s had the same name forever, and since the beginning, it’s had threads like the ones mentioned in the OP, so I don’t see the point. There’s something to be said for tradition, you know.
That was Field Marshal Haig’s response to people during WWI who suggested that climbing out of their trenches and slowly walking towards the enemy whilst under heavy machine-gun and artillery fire wasn’t working very well, too.
Another vote to keep it as is. It’s tradition, it’s unique to the SDMB, it’s got an attitude and tone that Cecil might use, and when a thread isn’t really Mundane or Pointless, I’m not distracted by the forum title.
