There is always the option of adding some new material, rewriting a bit, and marketing as an eBook to readers of the blog.
I thought about that at one time, but then I did some calculations about how many stories I'd written, screening out 90% of them for quality and figured I just didn't have enough material yet. I'll keep it in mind for the future, though.

PS - Plus, for the time I'd spend and the readership I've got, we're looking at maybe making five bucks.
PPS - I guess five is bigger than zero, though.
Well, a lot depends on the value you assign the experience. If it's something you think you'll only do once, it's probably not worth it. Like the first time at anything, it will probably consume too much effort, cost to much money and you'll almost certainly screw it up to some degree. At least, that's what the self-publishers I've heard tend to say.
However, if you're seriously considering this as a channel, or just want to publish books the way some people like to work on cars, build furniture, cook fancy meals, etc. then you might as well get that first one out of the way. Or maybe use it as a vehicle to discover that dealing with editors is actually much less trouble than you previously thought.
Disclaimer: I'm still at the "accumulating material" phase of this process, so you should probably take me with a large grain of salt.
