I've only posted one thing in SYW (well, two, but I wasn't talking about my query letter!) and the piece was something inspired by one of the monthly horror prompts. I received some really great advice for the piece, including an excellent suggestion to change the ending to an earlier section of the story (Thanks, Night!
).
Before I ever posted that story, I had given several crits, and I found that I enjoyed them. If and when I post something else in SYW, I don't expect any of the authors I critted for to crit my work. Sure, I would appreciate it, and I would think it was nice of them, but it's not something I expect. I think you'll get crits when you post, so don't stress over it.
Not being a professional writer I really hesitate to critique anyone's work although I am willing to contribute in any way I can. Does that make sense?
It does make sense, but critiques come in different forms. Some people go line-by-line (LBL) and pick up grammar or spelling mistakes, or make suggestions that they think might help a sentence or paragraph flow more easily, essentially giving the piece an edit. Others give their overall impressions, telling the author what they liked or didn't like and make suggestions that might help. Sometimes, they don't have anything to add because any issues they did have with the piece were already discussed by someone else. Then you have others who don't have anything more to say than they liked it, and they wanted the author to know they read it. There's nothing wrong with that, because sometimes we have to hear that someone liked something we wrote! (Geez . . . we're a needy lot, aren't we?
)
The point is, you're a reader and you know what YOU like and what you don't. Critting other people also helps you with your own writing because you'll catch things they missed and that has a tendency to help you catch those same mistakes in your work. It also makes you think about how YOU would handle a certain scene, or how you would word something differently to smooth the flow.
Just try it, you might like it!
