Thoughts rattle around my head all the time, good ones, bad ones, confusing ones, and the odd interesting one.
Two or three times a week I sit in front of a "blank page" in my text editor and start writing in the hope of getting some of those thoughts out of my head and onto the page. Sometimes I don't recognise them. Sometimes they look better, sometimes they look worse.
I try to make them intelligible to others, getting the right words in the right order, deciding where to put the paragraph breaks, hoping that they make sense.
And then I copy them into my various places on the web and press save...
... and seconds later they appear on your screen, you read them, and somehow the thoughts that were rattling around my head, only moments ago, are now rattling around yours.
This is a kind of magic.
