What's the average number of kudos?

I'm new at this and I know people have different preferences. I've been posting chapters over the last two weeks with certain themes in mind (pantyhose in particular in my case). My first two chapters did fairly well with kudos in the forties and fifties while the numbers went down after the third chapter, which was admittedly darker. Since then, despite things being lighter (and maybe a little kinkier) my kudos have been in the thirties. My last chapter only pulled 25 kudos but that's understandable as it's really a transitional (and thus not very erotic) chapter anyway.

Anyhow my question is... How many kudos and comments would be the barometer here to suggest that something you wrote had been successful? Also is there a way to attract people who are like minded who not only that would read your material, but you might have interest in reading theirs as well?
