Yes indeed it is and I am glad it is. You see some (such as I) have trouble with face to face communication. I can't explain why that is, and I can't say it is a scientific fact, but it is a fact.
I can converse much easier with the written word than I can vocally, face to face. I have a slow brain I guess, but I need time to pull together what I want to say . . . . to attempt to have it make any semblance of sense at all to another person. And sometimes even after spending time to pull my thoughts together it still makes little sense to another person. When speaking I do a lot of stumbling, trying to find a word that might communicate my thought to the other person in a coherant fashion.
I agree we should think about what we are going to say before we say it and I also think sometimes I think we should be silent. The forum format gives the time to post or respond to a post after a time of thought. We don't have to put our mouth in gear before the brain is fully engaged. This brings to mind the posts on time . . . . we creatures have it . . . . lets use it.
I spent some time on this and it may not make any sense but it is what I wrote so I am stuck with it.
A friend said recently that they would give me a "Christian rap' cd for my birthday. I was greatful that he would even think of me and I added if he could make sure the disc was of good quality so that it would last a long time as a drink coaster (coffee).
