Some constructive criticism:
The majority of these setups only really showed the tabletops. The next part to making a great setup is the Spec of whats driving the monitors.
What I love about the 'Post your mac setup' threads, is the entire environment these setups are in, the way people have used their ingenuity to get the right setup for themselves, how they may have built their own desks and whatnot.
I think what your blog needs is the story behind each of these photos (also it'd help to host your own images). You need to put in why you think these are the 25 best Mac set-ups.
Other than that, some nice linked pictures...
