How much does it matter, if at all, that texting and twittering treat spelling convention with little respect?

I read this question while filling an application the other day and felt it was worth sharing my thoughts on.

If you ask a layman today, “what is the fastest way to tell the world what you are up to?” They will either say texting on the phone or twittering, the two mediums have become the fastest and one of the most reliable sources of knowing the status of people around the world. Not only are they reliable but are very influential.

Now when we talk about these mediums treating the spelling convention with little respect, we need to think what’s more important to us, content or spelling.  Yes, I do agree that the language needs to be treated with respect, but where does that respect come from? What do you think is more important to respect a language? The spellings, or its ability to help you express your thoughts in the best possible way? English in fact, is respected as a global language. I think it’s more important to respect a language as a medium that helps us understand each other better rather than being stuck in the traditions of spelling each word right.

A language is meant to evolve.  It’s true that if enough people use words like “Grrrl” or “Muggle”, enough number of times, they end up in the dictionary. But who is complaining? As long as these words help Gen X communicate better, the respect has nowhere to go!
