Do you plan to share this spreadsheet?
Not sure if I will publicly — at least, I'm giving myself permission to keep it 100% private while I'm writing it up so that I don't end up subconsciously adjusting my predictions for public consumption
I think it's a good idea to keep it private while you're working on it. And it doesn't have to be a binary decision: you can share only the parts that are less contentious / personally risky, and keep the rest private (or share just with close friends).
There are benefits to sharing: many eyeballs make bugs shallow, etc. There are also costs. Sharing with only close friends may be the best trade-off for you personally: you get contrictive feedback and input, but don't expose yourself to all the trolls and bad actors of the world
Twitter may be over capacity or experiencing a momentary hiccup. Try again or visit Twitter Status for more information.
