For those who invest in Non-Pronounceable Quads and similar LLLL.coms in that range, its always good to have a "Plan B" unless you are a long term invester. If Plan A is to flip it for some profit soon, Plan B is to "develop" them. So while picking your names, do consider whether you can find some acronyms/uses for developing a site as a Plan B.
So initially execute Plan A (flipping) and if does not work out, fall back to plan B (developing).It need not be a full fledged site, mini-sites and blogs etc are perfectly fine.
Some of the LLLL.coms i have like CODH.com(call of duty hacks) ,DNMG.com ( Domain name magazine) , DNJN.com (domain name journal) were bought for flipping...but since the prices are coming down and i may not get the desired profit anytime soon , i can always develop them.
