Two friends want to read the next chapters of my novel and novella. I am working on (what I hope) is the last edit of my novel and will then have to spend many hours on the novella, improving it. Considering it takes so long to get feedback from people and two people seem really interested, should I just send them the work in progress anyway?
Do what you're comfortable with! If you want them to see it, then go ahead - but if you don't, then don't. I don't think there are ever really any hard and fast rules about showing people your stuff.
Personally I won't let anyone read something I'm not completely happy with. Having said that, I have the first couple of chapters of the current WIP posted on my website, and in my usual never-satisfied way they'll probably end up being edited again (and again, etc.)
So I guess it's up to you :)
