I have always wondered what amazon was thinking with that way of sorting. Perhaps it's a deliberate way to spread purchases out over a span of products instead of just the two top products?

I think it's about a product discovery. If we always sort this way, new products don't have a chance.

And I don't think Amazon would sort like this, it would make more sense for them to use hn/reddit way to sort items that give a chance for the new items to get to the top.

I also switched to fastmail from gmail. I setup gmail to forward all emails to my new address, and then running the gmail importer in fastmail. So i have all my emails in fastmail, and receive all emails sent to the old address. I'm using a custom domain for my emails.

This is exactly what I did. Also of interest is that Yubikey OTP is directly supported, you can host static websites (I generate my site with Jekyll and then rsync it to fastmail's web server), and you can have a ton of other aliases for your mailbox (I've got like 12 addresses right now that all point to fastmail).
