I have just rewritten an earlier blog. (See "punctuation marks".)  I guess that's allowed. Many writers describe the writing process as, simply, re-writing.  It's true, the hardest part of writing is getting the first words on paper or on the screen, as the case may be.  With the screen, first re-writing is often mere tweaking.  No, tweaking is never mere; it's fine-tuning.  Anyway, I cut and rewrote a blog. 

So, as I write this, I feel as if it's my second blog for the day. That's enough.
