I feel bad for removing good features, especially when they hurt only me. But in this case I cannot afford not to :(
1) Securing the whole site with SSL - this is great for everyone, and it doesn't really impact site performance. Turns out, though, it massively affects the AdSense income (as there are less SSL compliant ads out there), and I simply can't afford to take that hit right now. I've turned off SSL for unregistered and non Premium members, but it's still there for Premium members and on the login form for everyone (so that your login data is secure).
2) Credit card option for the Premium membership had to go. Not enough people opted in to this option for maintaining it to be worth it. I'll contact every user who got Premium through that to move them to PayPal.
Let me know how you feel about these and if any functionality is broken on the site for you today! I'm cleaning the fat here, so I can concentrate on cool new stuff, and I will - stay tuned! :) Cheers!
