I kind of like the color, although I guess it is an issue if some people have trouble reading it. But the color kind of makes the posts unique, as does the signature. How about just doing the signature in color, not the rest?

Best of Isola (Which we all already know)
Tabbeh (Because I'm not telling my real name)
(because I don't want to copy Maura)

Doesn't really work, does it?
