You can now link to individual dabblet revisions, which is ideal for tutorials. Check these revisions of the same dabblet:
To find the version hash of each revision, you have to visit the gist page (by clicking “View gist” on the menu) and click on the revision from the sidebar:
Then, take a look at the URL, the hash will be there, after the gist ID.
Of course the same functionality applies to the server-side generated results. Example: http://dabblet.com/result/gist/1695733/1e949dd3c1566124ef606cacd7fa8b5564502365
