I used to live for my correspondence, especially in the 1970's, when I became an obsessed Lovecraft fanboy and did things so as to emulate HPL. I would write up to ten letters a day, and some of them were excessively lengthy. When S. T. Joshi finally demanded I get email so that he could work with me as my editor on my collections, I vowed that I would still continue to write letters. But that didn't happen. And now I find it extremely difficult to find the motivation.
I used to curse the Internet because of this. "You've stopped people from writing each other, you fiend!" But, when I think of it, I am just as, if not more, communicative online that I have ever been, doing my blogs, my videos, responding in forums, reviewing at Amazon. It's the same kind of activity, but through a different medium. I've grown quite fond of it. For a crippled old queen who hates to leave home, having to go to the post office is an ordeal--but coming here is so easy, and quite rewarding.
