Pretty much anything that introduces your site to more people is a good thing. Create something good then tell others about it. That's the heart of cultivating traffic. This is something I am active in on multiple fronts, high and low tech.
Will it impact Google rankings? Perhaps indirectly. I like activities that contain a latent possibility for indirect impact.
