I have been a member of Scribophile for several years. I received both great critiques and poor critiques (usually a new member). Still, I have made several friends on this site. I use both Scribophile to get a critique and then present the same information to my in-person critique group. It works out great.
Since I moved to a smaller town, I do not have an in person critique group, this is a great site. Critiquing others works is not drudgery and it helps me improve my own writing. Other writers, particularly some newbies enjoy my insights. Others have given me great insights into my own work.
The site can use some more prefessionality in it's critiquers. Checking spelling and grammar is good, but in rewrites, that is often thrown out. Sentence structures and information is changed. Reading previous chapters is helpful to understand what you are criticquing. I appreciate those that take the time to check my histoical references or adjectives.
Posting critiques is easy. Answering a few questions then copy and paste. I like Scribophile and hope critiquers take their suggestions more seriously since they are given karma points whitch are easy to accumulate. Karma points are a great way to get works read. I've had no problem acumulating points nor using them.
Hope to see more professional writers on here.
