It is true that this name in itself is worth little in money, but if you ever come across a two word combination with a dash, that does have value in google results standings. Say you have another name you want to develop that is a more solid typin and branding name. Redirect your dash name to this other name (ex. link-directory). Why?
Because the dash (-) in a word is seen by google as a SPACE. This will lead to better indexing of that word combination over time and will help your traffic to your primary branding domain. Check google results for almost any word combo. You will see this tactic in wide use in http strings, and that is why. Just make sure to always use 301 redirects.
