Quite a question, isn't it? Since it's difficult to define 'greatest', maybe we could look at different metrics.

Aside from the LLO, the most viewed outpost thread is the NR, with nearly 4 times as many views as Wrem, its successor. The post-NR states account for a combined 28,061 views, while the rest of the outposts on the list (excluding LLO and NR) have a combined 21,845 views.The New Republic, the Second New Republic, and Avalon (Nfell's outpost) are the only outposts on this list to have their threads locked.by thread repliesThread replies indicate actual activity and discussion surrounding an outpost.The Last Light Outpost, 12,845 postsThe New Republic, 2,781 postsWrem, 587 postsThe Second New Republic, 564 postsThe Estonan Federation, 500 postsThe Sunstreak Islands, 454 postsLe Edeen Dur, 408 postsPazzo, 342 postsThe Nation of Volt, 227 postsLucky Pirate Crew, 189 postsSimilar results.

New Atlantia, the Lost City Outpost, the Crossroads Union, and the affectionately named Rainbow Butte all make an appearance, for the value of their detail or humor, which inspires enthusiasm.More stats will come soon! These are only forum stats, but I plan to measure outpost size, population and economy soon.
