As a matter of fact, this tells you one thing: As Hergé would have said one can (and one should) blog from 7 years old to 77 years old (and even beyond). In a sense, young people have a lot to "vocalize" and older (retired) people have a lot to share and a lot of time to share it.
Of course, blogs cannot do everything but there are a few things that they are truly good at and this is one of them: Breaking the "age wall".
By the way, welcome to a new blog dedicated to the management of change and, guess what, this is a blog from Algiers (Alger). MDI Alger is a Business School located in Algiers which is, in particular, very active in the field of executive education. Their aim is to make sure that the fruitful exchanges that get started when managers are on campus still blossom when managers are back in their offices. We are proud of the achievement as MDI-Alger belongs to the Cyberlibris community!
