Pelicans who have bad breaks.
At times most of us have had bad breaks. I have also discovered bad brakes on my car.
I can seldom do anything about the former. The latter I can repair.
If English is your second language, it usually shows up in grammar and I suspect your command of the English language is better than my grasp of your native tongue. You're usually trying though and I appreciate the effort.
Milt, I have to agree with you. Poor spelling and the misuse of words is annoying. I feel the biggest effect is the undermining of the message. If a poster is attempting to make me believe he or she knows what they're talking about, their misuse of words will dissuade me before they get there.
Remember: people are a highly socialized species. When we are speaking face to face, we depend heavily upon facial expression and body language.
If you remove the face-to-face and continue the conversation, we rely upon vocal intonation, speed and enunciation modifiers.
Once the vocal clues are removed from the communication, we have 26 letters and their capitals, punctuation and spacing left with which to communicate. This forum is a perfect example of that.
At that point, your whole communication is riding on the verbal message. It is easy to lose that message if you can't school yourself to use the tools in the correct fashion.
All the best.
