There have recently been discussions with a number of people about whether artists should have blogs on their websites. I encourage artists to have a blog on their website, and that they post to it at least once or twice per month.
A blog makes the website more dynamic. It gives readers—be it friends, family, or potential collectors—something new to see, keeping them up-to-date on works in progress, projects, exhibitions, or musings about your process. A really good blog can also inspire comments and conversations among other people.
One really good example is a blog by Suzanne Edminster, on her website, saltworkstudio.com, and in particular a recent posting titled Art Critique 101. Take a look and find out for yourself why it’s good. Let me know if you agree.
