Call Me A Snob If You WillI just can't stand coarse, poorly spelled writing. People always get more out of beautifully written pieces where you have clearly taken the time to put your feelings, experiences and desires down for all to see.
Using text speak does nothing for anyone.
I really admire people with a keen sense of humour writing with intelligence and style. One of my friends in particular is a writer of extraordinary talent. You won't see her writing rubbish because she is intelligent and cares enough to take the time to connect with her readers. With every piece she will leave you fulfilled and even wanting more. You don't lose anything by spending time on her writing - you gain something.
Relax, write how you feel. Realise that people are reading your thoughts and you may be pleasantly surprised with the feedback you receive.
