Interesting idea. Although compare this to a survey (most commonly used idea research tool): even with a survey with hundreds of responses, there is the question of the sample's representativeness. Here the sample base is so small that the results (positive or negative) just cannot be regarded as statistically significant. It may be used as a complementary tool to measure the "virality", but cannot give me a 100% confidence level within 0% margin of error.
