Long form writing, especially long form fiction, has aspirations to be relevant for a much longer time span than a post or comment.

One aspect of the v4v model on SN that doesnt work with such aspirations is that value and attention mostly goes to "fresh" content.

The long form fiction I've seen on here gets a bump of zaps in the first 12 hours, and then the zaps quickly fall off. Also, there is a bias in v4v toward new content. Very few readers seem willing to zap old fiction.

I'm not clear if this is true for readers as well (do you get 99% of your readers the first day as well?). Even though there are aggregation newsletters for ~BooksAndArticles, it seems difficult to garner attention after you publish. I suspect that this is particularly true on SN, but it applies to v4v in general.
