My experiment in massively curtailing my use of Twitter and Facebook is going well. Objectively, I'm completing more items on my to-do list on a daily basis; subjectively, it appears that my ability to focus has improved, which I'm willing to chalk up to not feeling compelled to check new-message notifications and therefore just not having that distraction, though I would like to be able to measure this in some way.
I was expecting to feel rather cut off from the world, but fortunately this has not been the case. I've been more responsive to more personal methods of contact (email, IM, in-person interaction) that I had previously felt spread too thin to deal with, and this has been hedonically rewarding (e.g., answering email from person asking for some software design advice -> nice thank-you email -> warm fuzzies).
I also started the Tiny Habits course that I saw mentioned in the Useful Habits Repository.
Are you using any tools to keep yourself cut off, or do you merely choose not to visit those sites?
