Back when I used Windows I modified my hosts file to make facebook.com redirect to 127.0.0.1.

That lasted for a few minutes.

I changed my password to something difficult to memorise which was stored in an online password vault. The result was it took an extra 20 seconds to login, which proved to be a very effective way to stop using facebook.

I just deleted the bookmark for Facebook so I have to type it in. Well, type "Fa" anyway. But just doing that instead of having a button to click cut down my usage by 70-80%. I was clicking the button out of boredom a lot, I guess.

I rarely use Facebook on my phone, I don't like the interface at all. Mostly I'll just use it to share a pic, and even then I'm going through Instagram to do it.

I've done the same (with autofill switched off in my password manager). Makes a real difference.

I should delete the app from my phone too. Or at least switch off all notifications and move it into a folder far away from the home screen.

It's funny, I did the exact same thing.

I haven't logged in Facebook for months because I'm too lazy to open my password manager and copy the password.

mine was something along the lines of "[myname]isaweasellylittle[swearword]". Super effective!

I was redirecting news.ycombinator.com to local host a few weeks back! It also lasted for a few minutes.

Oh I've been doing that with techcrunch.com for almost a year.

You need a compelling reason- a strong push or pull. Otherwise you're overcommitted in your current position. The in-between is a very distressing place to be. Decide on one or the other and commit to it wholeheartedly. You can always return and take the other path later. :)
