I truly appreciate everyone who takes the time to leave a legitimate comment here on my site. However, you should be aware that as one of the “poster children” for the I Follow Movement, I get lots of comments that are left purely for the link value and not to contribute to the discussion. I reserve the right to delete a link from a comment or to delete a comment all together if I feel it’s necessary. Also, if you leave keywords instead of your name in the name field, your comment will be deleted automatically. If I end up deleting the link from a comment that was well-intended, I apologize in advance, but I’m sure you’ll understand and you’ll be back to contribute again!
