I would think this depends on your overall intentions (goals) in photography. If showing your "best" work is your goal, and you want to leverage more sales.. I would hesitate to post too many shots anywhere. Somehow I would feel a bit like "Quantity vs Quality" comes into play here.. I might be wrong..

PS - I am no blog expert (I just barley started one).. you can see some of the way I am posting.. my "style" or whatever..
In 2006 I did a daily posting of interesting places in my city and it ended up being one of my best years financially. It generated a fair following and generated some publicity that is still paying off three years later.
