What is www.s0.gd?
We're just another URL shortening service. Granted, we're one that (as far as we know) has the best algorithm for creating those short URL's, and we're probably going to have other cool things added in the near future, but for now we're just like everyone else.
Do you do anything special?
Maybe? If you sign up for an account, you can use a personal URL which keep track of hits specifically to your link. That's somewhat important since we try and conserve links by re-using short URL's if we recognize it as an already active link. That just means if you and someone else post the same link, without the personalized URL you'll both be using the exact same shortened URL. We don't care and know that most of you probably don't either, but there's gotta be someone who does, right?
What are you adding?
We'll be adding some shiny statistical data for you to get with your URL's in the future (both global and personalized) including basic location mapping for visitors. I'd imagine there will be other things as well, just not sure what they are yet.
