Yagan Square Digital Tower

How often should I write a blog?

(I know I have written 3 just now, but that is purely to populate the website)

How often does a person want to read a Blog post?

Also, What about emails - is one newsletter a month about right? Just showing the latest paintings, events and exhibitions (and specials I suppose).

 (PS My artwork is up on the digital tower, in Yagan Square, Perth. 13 pieces)
