I joined my local writers group and got involved, becoming their blog director. Being new to this community, it was a great way to meet people and let them get to know me. They root for me because they know me. People can't root for you or support you if they don't know you exist.
Another thing I do is attend monthly gatherings at my local library to hear a featured writer / poet read their work. Afterward, there's an open mic. I often get up and read something I wrote. One, it's good practice, to get up in front of an audience and read my work. Two, it's gotten me notice. Three, it led to publishing some of those stories as free reads on the internet because of the great response I received for them. Fourth, applause now and again is a nice change of pace. I got my very first fan (not related to me or a friend, but just liked my work that much) this way.
I'll be reading later this month at an event sponsored by my local writers guild to promote my free reads. I used to dread reading in public, but practice has made me much more comfortable with it and much better at it.
I also volunteer. Every summer (I'm in the middle of my 4th summer), I docent at Pine Mountain Observatory as a star guide. I had a set of business cards printed with my website address, blog address and email, and I hand them out. Not to everyone, but to people I get into conversations with who then get curious about me and what I do.
So, yes, definitely leave the computer once in awhile and get out there and let people around you get to know you. It can be another very powerful tool in your arsenal.
