I remember when this was first published, I watched the video and then rushed to install plan9port and try Acme.  I used it for a couple of days before going back to Emacs, but Acme did leave a very positive impression on me.<p>- I really like how &quot;unixy&quot; of an editor it is; you can easily add new editing commands by writing a small program that reads from stdin and writes to stdout and use it to manipulate text within Acme.  Of course, that program could be a shell script, a Python program or a Java program; Acme only cares that it can give and receive text.<p>- The editor has a mount point that contains the configuration of the editor and this can also be manipulated by external programs to influence the editor.<p>- The concept of addresses (e.g. an address into a file, an email address, a URL, etc.) and being able to click on such an address and have the editor DWIM is very powerful.<p>- I still don&#x27;t know how to classify Acme: is it a minimal or a kitchen sink editor?  You can make it do anything you want, but out of the box it is extremely bare.  Is it a programmer&#x27;s editor or a general purpose editing tool?<p>I&#x27;m not leaving my trusty Emacs, but I&#x27;m happy that I took some time to get to know something that was completely different.
