I think that everything posted made a great deal of sense.

But, what about this? what if you added a little content? I am not 
saying your content is not good, however suppose you added a title to 
possibly grab a person's attention? I mean Les acteurs du projet informatique 
(chapitre 2/10) &middot;  Système d&#039;Information et Internet is kinda plain. 
You could peek at Yahoo's home page and watch how they write article titles 
to grab viewers to open the links. You might add a related video or a pic or two to grab readers excited about what you've got to say.
In my opinion, it would bring your posts a little livelier.
