[issue 138]()
 
#### Editor’s note
 
How can we know that the technology suggestions presented to us will be beneficial? In the world where tools, services and frameworks go through steady periods of hype, how do we critically assess their benefits and drawbacks? This task becomes near impossible when we don’t have the knowledge to judge on our own, and we’re facing strong persuasion (see this issue’s first article).
 
So many advertise as blazing fast, but, statistically, there’s a lot of room for performance improvements. Credible, up-to-date advice is hard to come by, and web performance education has a long way to go too. Everyone loves an easy win, but what we need is knowledge and a healthy dose of scepticism.
