Highly Recommend Helvetireader Theme (included in this addon) Rated 4 out of 5 stars

This is a good addon for changing the style of Google Reader.

I found the Hevetireader Theme (which is an option of this addon) to be far better than any Google Reader tweak that I have encountered, and I think that it would be far more popular if more people knew about it and tried it. Yes, everyone's tastes vary, but I find it much easier to simply read with Helvetireader.
