The roadmap is fairly general, not detailed enough, and not serious enough. It makes Stellar look like another startup, not like a company which wants to be the next paypal or replace bitcoin.
I think most of those cryptocurrency companies need to invest in their communication, PR and marketing in general. If they want to attract investors in their coin, they need to have a perfect communication, inspiring confidence. This would always be better than a stupid blogpost full of jokes...
But this is a forum of developers so I am not sure how this tribune for marketing is going to echo here ;)
