Unfortunately, there are a lot of questions on your list that there's no way in the world Q is going to answer (What’s the real story behind 9/11?, What really happened at Sandy Hook?, What really happened at Mandalay Bay?, What really happened at Whidbey Bay?, etc.).
It would be a waste of time and 8ch space to post them and of Q's time to read them. We need to narrow down the list to those questions that there's a great chance he would answer.
You make a great point about questions that Q either can't answer directly and unequivocally, or if he did, the answer would be nothing more than one more unsupported conclusion - and that certainly leading to more deeply invested "pro Q / anti Q" division.
The rate of questions put to Q on 8ch.net, when Q is posting, is hilarious! Everybody has their pet. When are chem trails going to be stopped?
Timing predictions are also iffy, just because timing/prediction is iffy in the real world. When will Flynn be cleared?
There are barriers to sharing insider info too. The other side sees every Q post we see.
The last Q & A was very entertaining. This one will be too. It's a great way to relive some pressure.
That’s why I proposed making a list. We can vote on what we’d most like answered.
Of course there is nothing that prevents anyone from asking whatever they like on 8ch.
Personally, I don’t think any of those questions are a waste of time. None of us knows what Q may or may not choose to answer.
