well just a quick answer: first of all suppo talks about coins for what he was paid for. price is 2 btc if i remember. devs want a price increasing, and suppoman are for some guys a indicator. i don't take him serious for introducing coins.
Suppoman looks very similar with mcafee try to shilling for altcoin. it will be more suitable to called it as promoting such coin rather than introduce it to the public. I remember suppo is created polling to the public audience to make FOMO to the majority of silent readers.
