Minor suggestion: The highlighting is a bit too obvious, and it seems a bit distracting for me. Can it be toned down a bit?

I personally find it fine, but it might be because I'm using the default theme, not the 2008 one. On the 2006 theme it goes from dark gray to light blue

Do you mean it will be based on the site CSS? That would mean on the 2006 theme there won't be alternating highlights, since almost every cell is the same color.

EDIT: Also if it's based on alternating post colors, this means it wouldn't work in any theme other than 2010. The only way to make it work would be to hard-code the colors for each theme or maybe have something like:

Line 1 color: post background #1
Line 2 color: post background #1 - (R=0C,G=0C,B=0C)

Some sort of pseudo code above, not sure how it would be in real code. Basically non-even lines colors would be based on Line 1 and the theme you use, but slightly darker.

Also note that eventually a new theme will be added again.

Ah ok, that should work.

Hmm... I don't like translucent stuff on my site. They slow the shit out of old computers down. I remember on MySpace such things would cause my browser to scroll at 1.5 frames per second.

On anything below dual-core and 256 MB video cards, the site will be unbrowsable.
