I don't know, it's very easy to blame the spelling, grammar & behaviour problems on the computer, but my partner is 47 has had to learn his spelling & grammar skills as an adult since the grammar school he went to never bothered to teach them. & myself, I was at school during the time when grammar was seen as a "hinderance to the development of creativity" or some such rubbish & one of my teachers got fired for having taught us basic grammar when I was 7years old. My daughter, however has excellent spelling & grammar, both in English & text/computer speak & she will spend up to 8hrs a day chatting to her friends all around the world on MSN & in forums, she also has an active & full social life & many 'real life' friends.
Myself I think every generation likes to find some technology or music or style of dress or whatever, to blame the lifestyle changes of the next, and to assume that these lifestyle changes are negative, often just because they're different. I remember my mother was convinced that I was going to turn into some sort of apathetic moron & never come out of my room because I listened to heavy metal music. And D&D was seen, litterally, as a tool of the devil to lure unsuspecting teens into eternal damnation.
My daughter turned 13yo today. She lives in a very different world than I did when I was 13, it is natural that her lifestyle is different, but I dont think that it is worse or unhealthy. So far she seems to be a happy, well balanced & well adapted young woman. Has the computer made a social difference to her life? Of course it has. When I went to live in Australia for a while when I was 10yo I didn't get to commumincate with my friends for the next 18months. Every day my daughter chats with friends all around the world, including her Nana who lives in westport. I was lucky to get a letter from my nana twice a year. Is it lovely to get a written letter or card? Yes, it's wonderful & every one of us can go out & send one any time we want, but we can also talk with our friends every day on email or MSN or the like if we choose. The computer has not killed the written word, it has merely increased our comunication options & I love not having to wait 6 weeks for a reply to a 'letter' sent to india
Are there literary difficulties in our schools? Yes, but they have always been there. John is highly intelligent & shows all the signs of having been a "gifted child" but he did not know what a vowel was & had never been taught the difference between a noun & a verb. And is this related to any specific country? No, of course not. In any country there are good schools & bad, good teachers & bad. Maybe, rather, the computer is just brining the problem more into the light. And maybe something will will be done. I hope so.
