"Typing is no reflection on intelligence, nor how "cool" you are."
Yes, I couldn't agreee more. A great many people with high IQs are bad typists. But you need more than a high IQ, you need emotional intelligence if you want to communicate well.
Reviewing what you write before hitting the "send" does show consideration for others and enable that you are understood/empathiesed with by more people.
You need to check that your message is not confusing, offensive (whoops, I failed that one!), repetitive or incomplete.
The beauty of email and the internet is that it's so quick and so powerful, but that is also its downfall, you can easily confuse/alienate/offend/bore lots of peoppe just by hitting that "send" button too soon.
Another point: people with OCD are ill, they're not just being fusspots or pedantic.
All I'm saying is if you have something to say and care about being understood, you should read it through before hitting the "send" button. In fact that that's all most people need to do. The message might take say 2 minutes rather than 1 minute to write, but it will reap rewards.
Off to bed now, it's getting late...
