Hi @techstack. From what I can tell, your little app allows users to grab the last number of posts that they written to speed up the process of tagging their posts in a new post. That way users can just click on the links rather than going back to the users blog to find the posts themselves. Interesting idea. I don't currently do that, so I won't have any need for an app like that. But for those that do link recent posts, it could be useful. Thank you for taking time to develop it.

@aggroed wrote a nice post about what a witness is as well. You can visit it here to help fill in more comprehension.
