Very nice design, a needed niche without a real competitor but... I think paying 16$ for stackoverflow trends is way too much to be realistic, I won't pay for it. I can get this information for free. and even more including HN trends, google trends and indeed job search trends, all this for fee, or with a few minutes googling.
