Mark emails me all the time with bugs he found in GoBlog (some that I would never have found myself) and features he would like to see (e.g. better display of Brid.gy webmentions). I take it as motivation and try to improve GoBlog in a way that it is useful for others as well. And I think there is a good progress.
But what will be the real challenge is to translate the answers and tips from our email conversation into documentation!
