It may be easy for you to remember but what separates that from any other LNN? There are endless combos just like L33. Ask yourself this...would you ever search for L33? Probabely not.
LLL/NNN are valuable as well as keywords like "party". It really must make sense though or else it's a waste without development :imho:
I suggest that you take the time to read posts and look around the forum at what others are buying and selling. You really can learn alot just from observing!
HI, it seems you are new here...
Maybe l33 is short and "memorable" but in itself it means nothing. It would take some serious branding effort to use that name so the value is not obvious. Besides the mobi namespace is not saturated to the point that there would be a demand for leet/hack names.
In a nutshell it's worth nil. Try to indentify some premium keywords that are available and usable then you a chance of finding a buyer.
