I have SSL enabled on one of my sites, (the one in my signature, to be specific) and I love it. I think having that green little "lock" makes it 10x cooler when visiting. Lol.
One thing to note, any images that are on the page once loaded that isn't loaded from either your server or another party that uses HTTPS will make your green lock go away. It's totally fine, though. I'm just saying, if someone links an image in their signature (or avatar) and the image isn't from a secured third party site, you'll just have this grey https:// next to your domain.
Other than that, I love it. Adds security while making your site look even better. 😀
