I came across a great article on blog tagline usage, you should check out
Wednesday, June 24th, 2009I was recently trying to explain some of these finer points to a client on writing to your audience and phrasing things to be more successful and reach more people through a blog. A colleague that I admire Timetheif at onecoolsite has done another excellent job on pointing out some straight forward information. You can read her full article here at http://onecoolsite.wordpress.com/2009/06/22/creating-an-effective-blog-tagline/ and let her know what you think and I am sure she will appreciate the feedback.
