This one really skirts the line between what's appropriate and what's not. The blogs feature is not intended as a place to advertise your products and on that basis alone, I deleted this particular entry.
If it had been posted by a regular person who also has other quality blog posts, I would probably not want to do anything, but in this case the person signed up specifically to post this one entry. It is unsolicited commercial advertising and that's not what the blogs are for.
