I keep getting comments from people along the lines of:  I just found you on Google search and added you to my Reader.  When I follow the links back to their web pages, they are marketing sites.  This is my blanket apology to all people who send such links:

I am more than willing to post your responses, and give you the links back you so desire.  But this blog has a minimum requirement for comments:  You have to show that you read the article, and then contribute something to a discussion on the topic at hand.  Note that just reading the article is not enough.  I am not going to make this a vehicle for spam.

If you are genuinely interested in the topic, by all means post, even if it is just to ask for more information.  I will certainly try to answer your question.  But again, don’t just fire off questions hoping to get the affiliate links.  I’m sorry, but that is just not how I am managing this site. The questions have to be something where the discussion would expand on the topic of the post.

I suspect that Google is smart enough at this point to identify blog sites and filter out links from them when calculating web page standings.
