A lot of people have started to use their own style sheets. Jesse Ezell gets the credit for the cool idea.

I would recommend you link to the external style sheet and not place the entire contents of the file into the news section. (please :D)

For a couple examples check out:

Hopefully, I can come up with a couple better looking default styles. If anyone is interested in making one of their style sheets available to everyone, please let me know and I will set it up as a new Skin/Template (you get the credit of course).

As Don pointed out, I tried to make all of the existing skins use the same set of style elements, so once you figure one of them out...you should be ready to go.

Please forward me anybad CSS/HTML you come across in the blogs. I am more than happy to update and would like to make the blogs as standards compliant as possible.
