Would you PLEASE, PLEASE STOP FUCKING WITH THE POST EDITOR? It seems as if you are determined to wreak havoc on those of us who switch back and forth between Visual mode and HTML mode.
This morning, for example, you implemented paragraphs as two line breaks, as you have done for ages.
This afternoon, you started using <p>…</p> tags… and you wrapped the whole post into one huge mass with few if any line breaks to guide the eye of the person editing the HTML.
And now you seem to be back to two line breaks.
Just STOP IT ALREADY!
