I know the only way to get better at this is to practice, so that's what I've been doing. I'm speaking up more and more when people ask for feedback, building up some karmic points so that at some point, I can post without feeling like I'm taking advantage of this great community of readers and authors.
Do you feel like your critiquing skills are lacking, or is it just me? How have you improved your skills? Was there anything in particular that helped you out, or is experience the best teacher? Please share your experiences in the comments!
