Are pro-Israel blogs effective?

Dave at Israellycool has an interesting poll that I would encourage you to answer. I wonder myself whether I have ever made anyone more pro-Israel as a result of reading this blog.

Even if I am "preaching to the choir," I think that there is at least one side-benefit of maintaining the blog, and that is that some source materials are out there on the Internet for when people are searching. Many of my "hits" are from people doing Google searches and hopefully a few more posts that are pro-Israel can affect opinions, even subliminally.
