Write Then Post, or Post as I Write?

My entry for the Summer Getaway contest is coming along nicely. I've got what I think are fun characters, a simple but fun plot, and some fun stuff planned for it.

So, I need to know: should I finish writing the entire thing before I start posting it? Or, should I post it as I write it?

Either way, you're getting a serial, because let's be honest here: serials get more reads and more comments. I'm looking at something that's going to be around, oh, 15 parts or so at most, and around 3k words a part. Posting, either way, is going to be a part every 3 days or so, and I WOULD wait until I had at least 4 parts ready to start. That leaves us with just the question of should I wait any longer than that.

What do y'all think? I know my ability to finish stories I start isn't the greatest, but I'm getting better about that, and I have a good feeling about this one. So, lemme know what you'd prefer.

Then I'll probably start posting it as I write it anyway, just 'cause I'm like that. But, hey, I'd still like to know what people want.
