There are lots of folks on this forum who have gotten sober using this community as their "meeting."
One advantage of AA is that you get to build sober friendships in real life. Also, as you grow to value those friendships, your accountability grows, because they expect you to stay sober.
Check out the secular forum for folks who work with the rational recovery ideas (there is a book). That approach is more about making a powerful decision in your life to stop drinking, without using the group model.
Bottom line, people are absolutely capable of quitting on their own or using an Internet community. If you go that route, you have to find a way to rebuild your life without the insta-community of support in AA.
You'll find a zillion approaches on these boards. It is an excellent place to start...
