A suggestion from @sebix to add the popular pingback and/or trackback support to acrylamid. While this is a great idea, it almost impossible to implement it in Acrylamid (at least bi-directional communication):
Sending pingbacks from a local workstation is easy to implement, nevertheless a local list of successful pingbacks, that have already been sent, has to be stored to avoid overhead. Additionally the user has to ensure, that the online version of the acrylamid-page is up2date for successful linking by the linked webpage. In my opinion every unsuccessful pingback can be either ignored (also saved in cache) or delayed (will be executed next time), the user can choose interactively.
Receiving all three types of Linkbacks require either Disqus (personally not the prefered way) or comment support by acrylamid (to be independent from third-party services) plus executables on the server.
So, I think the first step of solving this issue should be sending pingbacks, because it's the easy to implement and effective.
add experimental Pingback™ support, see #31
$ acrylamid ping
Pingback www.example.com from www.my.blog
$ acrylamid ping -10 # pings newest 10 entries
$ acrylamid ping -an # affects all entries, but due -n only
# show what would have been pinged
It actually works, so closing this.
