The list could go on and on. The best way to work on your idea is to turn it into a headline and improve this headline until it becomes irresistible. About that, I recommend you read through Carol Tice’s post Watch Me Write a Headline That Goes Viral where she walks you through the steps to optimizing a headline/idea into one that’s sure to go viral, and she shows you her thought process as she works on it. Another example is the post you are reading: my first idea was to answer the question “how can I know if my idea can go viral?” via a series of resources and expert quotes, but then I realized that would have been yet another round-up post and it would have offended the reader coming to look for an answer to their urgent problem. I worked on my idea until I came up with the six questions that I ask myself when I write for WHSR or my blogs, I edited my headline and… well, you are reading the results of that decision!
