There is a nowadays little known master of SF poetry living in the UK named Steve Sneyd.
He's (still) well-known among British SF poets, and also American SF poets who've been around awhile, but I, for one, had never heard of him until last year, when I was researching a Poetry Round Up on British SF Poetry. I have nominated him for the honor of Grandmaster of SF Poetry awarded by the SFPA (voting through June 15, 2015) and I sincerely hope he wins. It's important to remember poets like him.
He is pretty much completely offline and only writes handwritten letters or anything for that matter, including his SF Poetry newsletter DataDump. I interviewed him by snail mail and transcribed his hand-written responses:
