That was exactly the point I was trying to point out. FB is definitely a more compelling ad platform. However, Twitter's biggest challenges (since the IPO) have been wrt user growth. As such, I would have expected them to double down on their product/eng resourcing and build more compelling products vs spending large amount of $$ on their sales/marketing teams. Also, the recent trend is a concern as well where product/eng SBC spend (which was already low as a % vs FB) is going down while sales is going up.
