Every now and then I get an interesting comment for which a typekey id was used as a commenter id instead of an e-mail address. While that is perfectly all right in theory it unfortunately doesn't allow me in practice to reply to you by e-mail in addition to leaving a comment of my own below the poast. That's a bit unfortunate as most people probably won't check back on the blog to see if I have left a response. Therefore, dear readers, please put an e-mail address in the id section of the post if you would like to receive a response in case I have any 🙂 The e-mail address is only shown to me so there is no need to worry about spam. Thanks!
