It is curious how something like this gets published with inaccuracies like that Command-L will create an alias in Finder, when it is actually Control-Command-A.
I emailed Greg Joswiak about this (it’s cool how some of their leadership will respond to strangers’ emails: https://news.ycombinator.com/item?id=24055149) and he said the command had previously changed. It’ll be fixed soon on the site.
