This section on the opt-out subscription system may need to be updated:

Saidit's sub 'subscribe' system is an opt-out system, rather than reddit and voat's opt-in systems. This means that when your account is created, you're automatically subscribed to all subs, then you can unsubscribe from the ones you don't want on your home page. If you'd rather do it the other way around, you can go to 'preferences' in the top right to see your user preferences, then select the option 'unsubscribe from all subs' and you can build your own sub subscription list from scratch. This opt-out system also means that when you create a sub, any new users to saidit will automatically be subscribed to your sub.

After reading this, I was confused about why there were subs on SaidIt that I was not automatically subscribed to. I still don't understand quite how it works. I know I could go figure it out if I dug a bit, and this is not the highest priority improvement to saidit, but I thought I may as well mention that it's a bit confusing as it is now.
