As a writer, it is very rewarding to know that someone is reading your work. We scramble around and try to get published and get those "letters." Here we get that reinforcement we need and it is very rewarding to know we have an audience.
I try to read a lot of profiles, and Hubs and always comment. I answer questions, ask a few and try to post a time or two in the forums. Also you can "share" your work on your Facebook page which may get someone reading and following you.
