I wonder why more people aren't using them or why they don't get more of a mention. Is Cloudflare like the Walmart of these systems? LOL
I think it's because Cloudflare is more well known and a lot of web developer choose them for security & caching systems. Cloudflare originally worked on the Alexa(radar system). Their team also has a lot of experience working for other companies, so I'd say that sets them apart on that ground.

Matthew, Lee, and Michelle began to build the Cloudflare team. Recruiting before you have a product is always tricky, but one thing resonated with everyone: Cloudflare's core mission is to help build a better Internet. That was a project that smart engineers could get passionate about. Soon Cloudflare’s Palo Alto, CA offices began to fill with a talented team who hailed from top companies like Google, Yahoo, PayPal, and Mint.com.
The biggest concern that investors and advisors had was that Cloudflare’s solution, which was originally focused on securing websites, would introduce latency. The team became obsessed with stamping out latency anywhere in the system. In June 2010, Cloudflare quietly launched a private beta to select members of the Project Honey Pot community. The whole team held their breath. Then something surprising happened. Users began writing in that not only was Cloudflare protecting them against online bad guys, but their sites were loading, on average, 30% faster. The efficiency of Cloudflare’s system, the layer of caching for static resources, and the fact that Cloudflare was taking so much garbage traffic off its user’s sites meant Cloudflare not only offered security, it also offered incredible performance.
Today, we are launching a new dataset called Radar Rankings, where we identify the top most popular domains that reflect how people use the Internet globally and per country.

Cloudflare is used by major companies, so that gives them the leading advantage. Most people won't flock to a service that isn't well known nor talked about in the web developer community.
