I personally have a love/hate relationship with Critique Groups and Writers' Groups. When I lived on the other side of the mountain, I attended three groups and I loved them all. The first on was a sit-your- ass-in-a-chair-and-write group, the second was a-get-your-mind-working and workshop group, and the other was an editing group. What I loved about these groups were they had a variety of people and no one had the 'I'm better than you' attitude, the second group I attended with a traditionally published author. I remembering being in awe that she was so down to earth and willing to help aspiring authors. Those are the kind of people you want to find in a group, people who are willing to help and treat you as if you are on the same level as them. Each person has their strengths and their weaknesses, and you want a group to play off those.
So, Critique Groups? A good resource if you can find the right fit. So look around and see if you can't find one. You might be surprised. I'm still searching for a good fit, but I also have a string of beta readers to help me out.
