I am becoming more enamored of single purpose web sites, probably because the single purpose apps for the iphone are so handy. One service that fits the bill on the web is Write or Die. This service is aimed at people who want to write but find themselves easily distracted. In the age of twitter, facebook, blogs, email, IM, etc. that is a wide net to cast.
You simply put in a goal for your writing, either word count or a time count, or both. For instance, perhaps you want to write a blog post of about 200 words in 15 minutes; you enter those goals in the window. You can also select the mode of ‘corrective behavior.’ Gentle mode presents a pop-up message if you haven’t typed in twenty seconds whereas normal plays annoying sounds. The killer mode for now (since electric shock doesn’t work) is kamikaze mode. In this mode, if you don’t type for twenty seconds, the words start to auto-delete. There is a brief youtube clip on the service here.
A single purpose site, done well, helps you, the user, to get something done. Write or Die does just that.
