Why do so many people who write in this column, spell so badly and don't seem to know the English language?

Keep in mind, there are a lot of young kids and teenagers on here that mostly have the spelling errors and the weird slang. That's probably what you are seeing on here lately. You are right, though, it's hard to answer a question when somebody messes up most of their spelling or they use nothing but slang. It's nothing against anybody, and I like giving advice, but if people are serious about getting answers to  their questions, they would at least respect other fellow answerer's by using the "Check Spelling" option.

I hate it when people can't even spell or write in coherent sentences. They either must be THAT stupid or THAT careless. I have many "foreign" friends who write better English. \n\nI also hate those who try to push their religious views on others when someone asks a question outside of "religion and spirituality" or whatever the category is for that kind of talk :)

The spelling and grammar is awful, I agree. However, just because someone is typing in English doesn't necessarily mean that it is their first language.

I couldnt agree w/ you more.  I have found 2 reasons: 1. they are flat out lazy and dumb.  2. They have a very poor grasp of the english language.  If you cant read it, just report it and use the reason of bad spelling.  Its in the list.  Ive done it plenty of times and not ashamed to say it either.

People think that because they are on the Internet they don't have to spell things properly or edit what they have written.\n\nI've seen so many misspelled words and poor syntax on Yahoo Questions, and it's not just from EAASL (English As A Second Language) speakers.\n\nAlso some people think it's cool to hax0r talk.  Bunch of Un-l33t bastages if you ask me.

maybe because you are illiterate.

Because society allows them the ignorance. It's common and has almost become allowed to use incorrect grammar, or none at all! It's embarassing at time to those of us who have control of our language.

I'm hoping it's because some users are not English speakers. But I must admit,I'm appalled. The spelling and grammar are so bad,many questions are incomprehensible. As for spell check. I've never used it.

I agree with you.  Many of the people asking questions are not what you would call intelligent. They are minimally educated and haven't got a clue about spelling, punctuation and grammar. They don't even have enough intelligence to realise how important good spelling is.

I am fluent in English, Gibberish, Balderdash and Piffle, and I welcome the diversity of language found in the questions and answers posted here. \nYou should embrace the nonsense, it's not easy being an idiot - you've got to admire thier commitment (before they get committed).

LOL! I hear you. It is very annoying. And you're right, those people who pick at spelling mistakes are extremely annoying. No one's perfect.\nHave a nice day!

Because some people have far less maturity and brainpower than they do typing skills... and even those are mostly lacking.\n\n~~Naomi

I no wut you meen. :) People learn how to speak properly, they just don't care and forget how to do it. Lose/loose, your/you're, they're/their/there misspelligs are real annoying..

It's difficult to differentiate between those for whom English is a second language and those who simply cannot spell. I admire anyone who gives it their best shot. What I find more bothersome is the use of "chat speak". I admit that I am guilty of throwing in the old "lol" from time to time, but when I see so many people using an abbreviated version of the English language, I have to wonder if we haven't just become too lazy to use proper spelling.

People are lazy, ignorant, and apathetic.  Not only can they not bother to check their spelling, they don't seem to think it's worth the time.  If you can understand me, then that's all that matters, seems to be their thought process.  What they fail to realize is that by not checking their spelling, the poster is causing people to reduce their estimation of him/her.  It's sort of like people who drawl out their words...you know the kind.  Every four letter word has two syllables?  Now, they might be the smartest person in the room, but you can't help but knock off a few IQ points when you hear them speak.
