I've used this analogy before, but threads is like a huge, 5k passenger cruise ship docking in a small town in Alaska. You don't have to know ahead of time that the 2 public bathrooms, one at the general store and the other at McDonalds, aren't going to be enough. You can also forecast the complaining about how everything isn't really tourist ready. It will suck for everyone. The small museum will be overrun and damaged, the people will be treated like dirt. It's an easy forecast.

Here's the important bit, just because they've never been in the cruise line business, doesn't mean you have to give them a chance to ruin your town.

edit: made sentence make sense.
