A friend recently asked, "I'm a visual artist, why should I write a blog and if I did what would I write about?". Those are good questions. The first one is pretty easy for me to answer, the second takes a little more thought.
It's about building an audience
As visual artists we like to think that our work "speaks" for itself. That indeed may be true but if no one sees that work it's message may not reach the audience it deserves. If you are in the business of art, meaning you want to sell your work, or even if you just want people to see it, then a blog is an effective way to share your motivation, experiences, travels, expertise and, not least of all, your art work with a larger audience. Simply put, it's an opportunity to connect with a wider audience and build a community of those that are interested in you, your work and your art career.
