Отрицательные стороны интернет-общения: 

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.

Brest is a beautiful old city on the west of Belarus. It is a city and administrative center of the Brest region of the Republic of Belarus. The city is located on the right bank of the Western Boog River. Brest is a big economic and cultural center. It is also an important rail-way and auto-road node. Brest was first mentioned in 1019 as Bierascie. It is believed that ancient city's name comes either from the word "bierast" or from the word "bierasta". The city's name was changed several times during its history. At the beginning of the 18th century the city's ancient name was changed into Brest-Litowsk. New name lived till the beginning of the 20th century when its second part was discarded, and the city has become simply Brest. In Brest there are many museums, two theaters, one skating-rink, two universities, five gymnasiums and one lyceum. The fortress is the main attraction of the city. The history of this defensive construction started in 1842 when the entire city of Brest was moved 3 kilometers east, and on its place a massive fortress was set up. The fortress made a prolonged defense against Germans in 1941 and was ruined in the result of severe battles. After the war the remains of the fortress were turned into a grandiose memorial to its defenders. At present near 300,000 people live in Brest. It is a big economic center because it's situated on the border of Belarus and Poland. There are many beautiful new and old buildings. I like my native city Brest very much!
