I was curious today, and I decided to check the Google trends page and see what's going on with CakePHP.
Apparently, even though CakePHP is not covered by the media as much as RoR is, Cake is getting pretty close. Well, at least according to this graph:
I've included CodeIgniter, because it seems like people have doubts whether to use CI or Cake. I haven't tried CI myself, but I can recommend CakePHP any time of the day (and I do whenever I get the chance).
Since CakePHP is not hyped as much as RoR is, I think it is safe to assume that CakePHP is getting popular because it is good. And people tend to share the good things in their lives.
That being said, word of mouth is probably the best advertising weapon we have. We all know how good Cake really is, so spread the word, talk about it, make people try it out.
If you have your own site or are a member of a community, inform people, post links, write articles. RoR is obviously going down in popularity, and Cake should be the one to take the throne.
Speaking of thrones, when is CakePHP 1.2 going to take The Stable Throne? Anyone has any intel?
