For those who have enough self-awareness to understand their limitations, but low reservoirs of self-discipline when it comes to keeping off the net, there is (first time writing this worn phrase) an app for that: http://macfreedom.com Used by more than a few writers who need that one additional disincentive to stay off the web. Silly? Yes. Useful to some? Probably. For some it may just function as a way to schedule your writing time - like a stopwatch.

Thanks for that, Brian. It's the nature of the beast, the web is both ally and enemy, the latter when it lures us into Link Hell. Programs like macfreedom are necessary for some to enforce us to create a space within which to write.
