One proven strategy for creative writers to get something flowing is to use writing prompts (one prompts site–mouse over a number to see a prompt). The immediate output of writing to a prompt may not be particularly valuable, but it gets juices flowing.
Are there any “programming prompts sites” designed to help the visitor get to an idea of a project and get into that hacking, tinkering state where you make one enhancement and then another enhancement presents itself?
The problem is that this sounds like a random startup generator http://www.ykombinator.com/ – I’ve seen similar sites to the ykombinator one but can’t find them right now.
