Yes, being active on HubPages helps get you noticed, as does posting on social networking sites like facebook. But you also want to think about what subjects you're posting. For example, if you post hubs about gardening, it would be wise to join an online gardening club or website and post links to your gardening articles on them. I write a lot of graphic design articles so I try to post links to my articles on art communities and websites. So figure out what your target audience is then go in search of that audience online.
