Given the nature of the ideas/plots/etc., most (not all) tend to be about two to three thousand words worth.
I tend to disagree, at least I think there are quite a number of spanking stories I have read that were much longer than 3000 words and needed to be. My own "Jane comes to the Institute" is really a single story of about 15,000 words, and while it could probably be cut some, I don't think it could be cut much below 12,000 at best. Here I posted it in 6 parts, but it was originally written and sold (yes it was once published commercially by CF Publications) as a single story. I just read "Exchange Student Surprise" in 19 parts (over 75,000 words) and it kept me clicking for the next part every time, and indeed I want more. Lurking Dragon's 'Melody" series was posted in something like 60 parts, and it had rather little fluff in it in my view. (I wish it were here on the Library.) Those are just the first three that come to mind.
