I've also been visiting/investigating various other groups in the area. It's amazing how diverse they are. One group doesn't let people submit their work until they've been attending regularly for months. One group only lets multi-published authors in. Some groups don't allow homework (you read and critique on the spot), some groups have lots of homework. The bottom line here is: if you're interested in finding a critique group, you may have to try out a few different ones to find a good fit.
But let's back up a bit. If you don't have a critique group, how do you find one? Many libraries have in-person critique groups. The internet has a ton of groups. I've heard good things about Critters Workshop, but they do focus on speculative fiction. I know the Rocky Mountain Fiction Writers have a good on-line critique group. When considering a group, things to consider include: Are the meeting times and locations convenient? Are they experienced in your genre? Is the amount of homework reasonable? Are the comments you receive helpful? Are your personalities reasonably compatible? Is your writing better as a result of their input? Your-question-here.
