how's it going?
you ask another good question, that i'm not sure i can answer. how do the powers that be define legit? my guess would be if it's something that pays or is well known (not fly by night), just like in hard copy.
i can say that i have a publishing history if i've been published in magazines, periodicals, whatever, legitimate outlets where i've either been paid with money, or perhaps copies, depending on the source.
as you know, i'm (slowly) putting together a compilation of poetry and short stories, that you are a part of. is this little periodical a publishing credit? my guess is that you can count it as such, but it may not carry much weight if the publisher you are trying to sell your stuff to has never heard of it and it means nothing to him or her. what matters the most, unfortunately, is not what WE as writers view as being published, but what THEY view as published.
then again (the way i look at it) it wouldn't hurt, would it? it could look good on a publishing history and start to get you in the door at other more legit places and then you build on that. in other words, you can say you have a publishing history when my rag, OPUS, gets printed. but it looks much better if you have a publishing credit of say STORY, or AMERICAN POETRY REVIEW, you get the drift? noone's ever heard of OPUS except the 50 people that will end up with a copy, ha!
i guess in the end, whatever 'rules' apply to the regular publishing world, applies to cyberspace. that's the way it seems right now, but maybe it will change in the future? maybe people like us will force a change? who knows?
also, and i hate to admit this but it's true, the more 'legit' a pub credit is, the better the writing caliber is, and publishers are VERY aware of this fact.
hope this helps! (i think i'm more confused than ever!)
