FWIW, I&#x27;ve found the Leechblock plugin (and probably many others like it) to be a great help. I&#x27;m only allowed on FB and similar time-sucking sites (HN not included....) after 9pm. But I think it ultimately doesn&#x27;t help unless you acknowledge the problem, as they say in AA. You&#x27;re going to find ways of circumventing plugins like that, for me they mostly help in curbing the &#x27;reflex&#x27; of typing in facebook.com in the address field. For that, it&#x27;s great.<p>Also curious to know how helpful the HN crowd finds Twitter for actual networking purposes.
