When you write short stories and submit them to various and sundry publishers, you start a waiting game that can last months. Of course, some publishers are on top of things and get back to you very quickly. I've even got responses in a couple of hours. Nice to get a response. Not as nice to have the response be a "no thanks."
But, the painful ones are those that drag on into months. I've mentioned Duotrope before (see links). They provide a submission tracker that an author can use to enter and track responses on her story. They also provide statistics on the various publications when they have them. I hesitate to submit to a magazine whose response time is 180 days and that one submission in the stats was a rejection. Seems like I'd be wasting my time to send my precious story off to those cold-hearted types.
There's another statistical tracking site, called Submitting to the Blackhole, that might have more information than Duotrope. The only problem is that it tracks specifically science fiction, fantasy, and horror publications. Still, it has a lot of them and you can get an idea of how long a specific publisher usually takes to accept or reject a submission.
I'll add Blackhole to my links list in case anybody would like to take a look.
