There are so many ways to have an online presence these days, and it takes a lot of effort keeping them all updated. I don't really enjoy Facebook, so I save that for keeping up with closer friends (and hardly ever post anything). I do use Twitter and Instagram, but quite sparingly. I find them both a lot more user friendly than Facebook, and it's fun searching through images and tweets, but I don't post as often as I'd like. Pinterest is another of my favourite websites - I have loads of boards now. I've always been a big fan of a mood board!
I also have a page on portfoliobox.me which is basically a small portfolio of my photography and a place to keep all my links together.
How do you keep up with your online presence? Without it taking over your real life? Do you find it more of a hindrance than a help?
