I've tried introducing family and friends to my various sites, but they simply are not interested. I've done it through different ways, starting off with a message on Facebook, showing memes on my wall, and even going as far as showing them the site myself when I'm with them. I have this sense that there are people in life who don't like forums (why?).
My family is very narrowminded toward the whole web development thing. In that case, I don't market to them. In fact, they would only know about some big wins I might post on Facebook.
I have multiple pages on Facebook and I have friends and family as followers. So when I post on my page, my content will reach the feed of my friends and family.
