What's wrong is, stop and think for a moment, when was the last time you picked up a book or a magazine and saw that it was printed in a ridiculous centered red font. (I'd guess never)whats rong with center allignment? its neater nothing wrong with red and its not that hard to read LCDs show red nicely
There is a reason for the normal left justified common black fonts, they are easily readable and can hold your attention for longer periods without tiring the eyes.
You would be well advised to stick to the norm, if in the long run you want your posts to be taken seriously.
