I do read all posts before posting myself even if the thread is ten pages long. However, sometimes I tend to speed read and miss things. When I start a thread I always try to follow through with it and respond to the other replies.
I, too, am bothered by poor grammar. I can't help it, but I'm more drawn to the posts written by people who I know will post something I can understand. Yes, Amy, such as Bill. He probably thinks I stalk him! The mistakes that get to me the most are the misuse of "their", "there" and "they're" and when "loose" is used for "lose".
I think most people read threads but a lot of forums skim the replies or the posts before posting their own thoughts, which I think is what you are referring. I think that's where the info gets missed and not so much unread.
For me, I always read the whole thread before replying, although I do speed read if nothing keeps my interest. When I create a thread I always check back to read the replies that I've gotten because I feel that it's my responsibility to do so.
I think out of all the threads I read, I only reply to one fourth of them. I just like reading about horse related things. :P
I never use spell check on here, but I will pull up Microsoft Word if a word has me stumped on the spelling. And yeah, I abhor chatspeak. XP
Well, it depends on the thread whether or not I read all the posts. For instance, this thread: I started to read them all, but determined that this was really about what *I* do and not an "advice" column so I skimmed most of the replies, but not all. Figured what others had already written didn't matter to my reply. Also I try to stay on the shorter threads. I just don't have the stamina to read 20 posts, esp. With some of the grammar and shortforms that are used. Sometimes I'll start on a thread, it'll get really busy and I'll drop out.
Spell check? Well I usually don't use it because I'm on dial up and it just takes too long. Hopefully my typing isn't too bad.
On "I'm looking for help" threads, I will read what's already been posted and generally stay tuned for future happenings. I learn quite a bit that way I find. Also, it's nice to see posters agreeing or disagreeing with what's been said elsewhere -- gives a nice idea of "general consensus" or "average".
Interesting replies but most seem to be on the same page regarding text speak. I guess it is in my case being out in the business world that if anything came across my desk in that manner it ends up in the garbage.
I certainly understand it on cell phones but when I see proper names not capitalized or things like "u" I feel the the person that can't take the time to respect the reader deserves no respect in return.
