Best by far that I've found is SelfControl by Steve Lambert - thanks Steve! http://visitsteve.com/made/selfcontrol/ http://visitsteve.com/made/selfcontrol/ It's OSX only though I'm afraid. It blocks at the network driver level and survives a restart. I switch it on for two hours or more, after one check of my email, before starting work in the morning. This initial two hours of inability to visit distracting sites usually gets me in the groove with whatever I'm working on. I then find I'm less likely to get distracted throughout the rest of the day and more able to stay focused on my daily task list. I've been developing a system designed to get my procrastination under control. Fifty percent of this procrastination takes the form of reading posts from HN. So I feel your pain! My system is based on a modified version of Bill Westerman's GSD system (http://www.utilware.com/gsd3.html http://www.utilware.com/gsd3.html). I've got a draft blog post that describes it and the software I have used recently to help me focus. It's helped me finally get round to building what I think is going to turn into a pretty useful app for managing résumés. I'll post a link to the blog article soon so keep an eye out for it here on HN.
