How many people are actively developing Phalcon?

I have noticed that very few people are active here on the forum. Especially not so many expert users. My questions regarding Phalcon developers:

1) How many developers are actively developing Phalcon right now?

2) How many was developing Phalcon a year ago?

There are no accurate numbers at the moment because we have two concurrent versions going on.

The core team can be seen in our website here:

Vladimir (sjinks) used to be part of our team but due to personal reasons he had to step down at least for the time being. This team works both on 1.x and 2.0 versions.

Additionally for the 2.0 version there are a number of contributors as seen in our cphalcon repo (switch to 2.0 branch)
