This website is quite fun, except it has (for me) one fatal flaw - if I use the automated stuff I am stuck with whatever name someone else decided to give the alias.
Nope feel free to create another alias. Aliases can be voted up or down so eventually over time the best ones will rise to the top. Also if you want it on your profile just add it.
We did think about this and plan on adding private aliases soon so you can add them without cluttering the site or if you just don't want to share. :)
For example, http://alias.sh/open-any-file-default-command-file I find so useful I shorted the alias to 'o'. Now, I could make another alias with a different name, but that seems like a bad idea..
