Why are you writing in English - your native language is used by enough people that you could be successful by focussing on it alone. Sentences like this are so clumsy to read that you either need to find someone to proof read your articles or publish in French. If you were tackling a niche from a unique perspective then clumsy writing might be tolerated but your content is no different to a gazillion other blogs. Find a business plan template and go through the process for your site. Treat it like a business whose goal might be to earn money build your professional reputation become internet famous be an enjoyable hobby You need to be sure you're taking the right approach to meeting those goals
Your website looked informative. But it is a bit clumsy to navigate through. A lot of info on very little space makes it looked cramped. I suggest that instead of having so many menu options, categorize them and add them as sub-menus. On landing page, 'TAGS' part is taking up 1/4th of the page. I suggest you push it to the bottom of the page, all the way down.
