Miss Eggy,
I would whole heartedly agree if Ranaan were writing poetry or was trying to find his own style with fiction. However, he is communicating in a public forum. I have appreciated Ranaan's postings and I have received value from them. However, some days I just don't have the energy/attention/patience to decipher the shorthand.
One of the concepts in NLP (neuro-linguistic programming) is that the meaning of a communication is the response that it gets. The basic idea is that you are responsible for making sure that people understand what you are trying to say. If there is a failure in communication, it is your fault, not theirs. It isn't because they are stupid or bigoted or unyielding or whatever. It's because you didn't take the time to figure out how best to present your idea.
In a public forum like this, there are people from all walks of life and many nationalities. Since we can't be sure what their background is with English, it is best to write at a level that is most likely to be meaningful for the widest audience. Shorthand is typically useful only after you have attained a certain level of mastery of a subject. (Of course, there are also lazy people like me who just don't want to put that much work into reading the postings here).
Also, a person's writing abilities do tend to have an impact on the credibility they are given. I know that Ranaan has great insights and he also has excellent communication skills. By combining the two, he has so much more to offer the group. In presenting his ideas clearly, he multiplies the value to all of us.
Ranaan, I have benefitted from your posts and I will continue to do so. You always have something to offer that enhances my understanding. I look forward to not having to work so hard to get that from you.
