Social Dominance calculates the "share of voice" across all social media data.
This is similar to Market Dominance however instead of dividing a coins market cap by the entire cryptocurrency market, we divide a coins social volume by the entire cryptocurrency market's social volume.
Bitcoin Social Volume: 1,000,000 mentions
Entire Cryptocurrency Market Social Volume: 10,000,000 mentions
1,000,000/10,000,000 = 10%
Bitcoin Social Dominance in this example would be = 10%
