About a month ago, Sean Kleefeld wrote a blog post called "My Short Career as a Letterhack," in which he talks about writing to comic book letters pages in order to get on the radar of editors. I can relate, because when I first got it into my head that I wanted to write comics, that was an approach I took too.
For me, it wasn't so much about being remembered by editors as it was simply a way of connecting to the comics industry on a deeper level than just reading the books. I started seeing some of the same names pop up on comics pages a lot (possibly even Sean's; I know I read at least those Marvel Knights issues he was published in) and figured that I could do that too. And since it would mean submitting a piece of writing to an editor and competing with other pieces of writing for print, I saw it as sort of a first step towards being published.
Sean posted a cover gallery of comics that his letters appeared in, so I'm doing that too. My time writing letters was much shorter than his, ended when I got reliable access to the Internet and was able to write about comics that way. But I had a good time with it and was able to figure out what kinds of letters editors were looking for.
Milestone had a Letter of the Month deal where they'd send one letter-writer a signed copy of the issue in which he or she was printed. I got picked for talking not only about Hardware, but Milestone in general and what it meant to me.
I grew up a Marvel kid, but tried a bunch of DC comics shortly after their Zero Hour event and wrote in to tell them about that.
I was a huuuuge Azrael fan, and loved getting to gush about that character to the folks making comics about him at the time. Sadly, the series didn't stay awesome it's whole run, but the issues with Barry Kitson on art were amazing.
I'm also really happy that I got to tell Peter David and Company how cool their Aquaman was.
My last published letter was the nerdiest of all as I expressed my appreciation that Malibu's Deep Space Nine series offered a more plausible explanation for the existence of Thomas Riker than Star Trek: TNG did on TV.
