Here's another google you can do to find WP blogs that give some link juice.

KeywordLuv is a WP plugin that allows visitors to use their name and keywords when the post a comment, but only the KEYWORDS will be used as anchor text in the link they give.

The purpose of the KeywordLuv plugin is to reward people that post a comment.

To find blogs using KeywordLuv, use the following search phrase:

keywords "enter yourname@yourkeywords in the name field to take advantage."

Note: only substitute your keywords for the keywords in bold. Everything in quotes should stay as it is, as this is the fingerprint left by the KeywordLuv plug in.

Here's an example search using <health> as the keyword:
http://www.google.com/search?sourceid=navclient&ie=UTF-8&rlz=1T4GGIH_enUS274US274&q=health+%22enter+yourname@yourkeywords+in+the+name+field+to+take+advantage.%22

In this example, in the name field when we're filling out comments, we'd enter:
Kurt@health

This lets us input our name, but doesn't include it in the anchor text.

Please take the time to add a useful comment. I think that's a fair trade.

PS. Don't forget that you can use the PR search engine so you can see the PR of the comments pages. It returns google SERPs + the PR.

Also, try these type searches in Yahoo and Bing to get a wider variety of blogs to post on.
