There are many reasons to learn English, but because it is one of the most difficult languages to learn it is important to focus on exactly why it is you want to learn English. If you know English well, an incredible amount of resources becomes accessible: books, courses, videos and of course, a great part of the Internet. Many positions require dealing with clients, service providers or colleagues from other countries. In those cases, your knowledge of English is a critical advantage. It can help you advance further in your career. You can speak with confidence and get your message across clearly, instead of hesitating and stammering. Well, it's a GLOBAL LANGUAGE. As an example, a German person and a Mexican person can communicate using English. They usually wouldn't communicate using Bulgarian...
1) "Упрощение" языка за счет использования символов-эмодзи, картинок-мемов и различных жаргонных выражений, призванных сократить число символов в предложении;
2) Различные формы заимствования интеллектуальной собственности (как правило, что попало в Интернет-уже "общественное достояние");
3) Замещение реальных контактов с живыми людьми виртуальными "друзьями", поощрение социофобий, соблазн создания виртуальной личности с "идеальной" жизнью.
Конечно, это далеко не полный список возможностей и последствий, а только мое видение данной темы.
Negative aspects of Internet communication:
1) "Simplification" of the language through the use of symbols-emoji, picture memes and various slang expressions, designed to reduce the number of characters in the sentence;
2) Various forms of borrowing intellectual property (as a rule, what has got into the Internet is already "public domain");
3) Substituting real contacts with living people with virtual "friends", encouraging social phobias, the temptation to create a virtual person with an "ideal" life.
Of course, this is far from a complete list of opportunities and consequences, but only my vision of this topic.
