“They taste absolutely terrible” That’s your opinion, I personally think it tastes great and haven’t had issues drinking it over the past 4 years. Given that Soylent has continues to grow signals that other consumers agree (investors also agree given they’ve raised $50m led google ventures). Also your product costs $12 per 500 cal (vs. $2.42 for 400cal for soylent) which is a huge selling point for people that drink…
Your statement that it’s “affordable” is valid only the sense that it’s cheaper per calorie. Declaring it “better” without qualifiers is, to use your own words, “your opinion”, and declaring it “convenient” presumes that it is nutritionally valuable to all, which in my case and in this founder’s case, it cannot be for flavor or digestive rejection reasons.
Please take more care when declaring your opinion not to misrepresent it as fact. Evangelizing a competing product in a Show HN isn’t going to earn you much favor to begin with, and misleading people by stating opinions as fact will only undercut your message further.
