On what planet can you come off comparing Shopify and Herbalife? Shopify is a software platform around which a healthy eco-system of supporting software and business potential is developing. One can argue that Shopify is overpriced but using Herbalife as a comparison is absurd. 
The Citron attack is foolish and short-sighted. At it's core Citron's argument is analogous to claiming that if dubious companies make money from unrealistic SEO or E-Commerce promises, Google and Amazon should be investigated and their stock heavily shorted. Mr. Milstead, please use statistics and real data and do not fall into the anecdotal arguments  presented by Citron.
