I've been enjoying the accolades and kind advice, much appreciated, but you all missed my point.
"I am leaving" means I am leaving. "I am leaving I am leaving", particularly with reference to the Paul Simon song, means I ought to leave for my own health and sanity, but probably, knowing myself, I am not.
However, my online presence is going to change a bit. Expect fewer and shorter contributions for a while, while a new project is in the works.
The only thing we can be sure of about the future is that it will be absolutely fantastic. So if what I say now seems to you to be very reasonable, then I have failed completely. Only if what I tell you appears absolutely unbelievable, have we any chance of visualizing the future as it really will happen.
