There’s not much difference these days, imo. I use tor for everything and don’t notice any reduction in speed. 20 years ago, that wasn’t the case, but residential internet is a lot faster now.

Tags are great, too.

I love KISS.

The inability to add the account to a standard email client is why I stopped using them. Electron Mail exists now, which is an improvement, but I still have to download each email and import them into my client.
