Long time ago I could read and learn about web development in Russian only. Later, having completed an English language course, I began to read articles and blogs in English more and more. The same went for conferences: I visited
Russian-speaking conferences at first and later switched to English-speaking conferences in Europe. In both articles and conference talks, I noticed how the content was different depending on the language used. Sometime I even thought that the communities evolve in different ways and follow different directions.
