A big thanks to Lynn Terry for pointing me to the WordPress app on the Droid, and suggesting that I could create posts by talking into the Droid when away from my computer.
I am doing this now. The hard part is to not edit what I say and to save the editing function for when I'm at my computer. (If you're reading these words, it means the editing has been done.)
By doing this I can create posts on the fly whenever I think of something and save it as a draft to be polished (to whatever extent) later. Or if urgency exceeds polish, I can post right away and clean it up afterward when I have time.
This is definitely a skill to master.
I suggest you visit Lynn Terry at ClickNewz.com.
