Welcome Rob,
Stick around for a bit, if AA is something you're interested in give it a go. As others have said you can just listen if you want. More than likely someone or a few May approach you before or after a meeting, they like to welcome new comers in my experience. It works for many but wasn't for me. There is no right or wrong way to getting sober, it's as varied as each person who's working toward sobriety.
Best if luck to you.
