In one of my previous posts, I had included some links to interesting sites where figures on sales were published and discussed. Remember those?
Now, do you want to know more about what "indies" should and souldn't expect? Well, if your answer is "yes", an I'll bet your answer is "yes", just read Jeff Tunnell's article.
Browsing the web I happened to find this site which is really interesting and instructive. Ok, enough talking ... just go, read the article and do the math.
See ya ...
