It is becoming a letter about water, which is not what you subscribed to
Why
Because everything I have found interesting for eighteen months has been about water, and pretending otherwise produces dutiful writing.
What changes
The subject. The length, the frequency, and the absence of advertising all stay exactly as they are.
What to do
Leaving is entirely reasonable and I would rather you left than stayed out of politeness. The archive stays up for everybody either way.
