The Secret Sun did a post (So) a short while ago highlighting an advertisement inside a 1977 (Elvis's Death, New York blackouts, Summer of Sam) Playboy. 
The 'So' forms the synchromystic Stargate symbol (O) atop the 911 Mega Ritual's Pillarmids (towering pillar and pyramid symbols). Perfect symbolism of the consciousness focusing force unleashed on September 11th 2001.
The 'Lost' island has been synchromystically shown to be a symbolic Island of Manhatum (Manhattan as symbolic mound of Atum (See Island of Atum)). This was explored in depth (see Comic Book Cycle 5 A and B) and will probably feature again as the new season gets into full swing.
The last thing we see of the intro title before the show officially starts every episode is OS. Synchromytically anything goes (if you can sell it well, we will buy it, no problem) and OS very easily being SO..."Lost" also saw an episode titled "Enter 77" (see Comic Book Cycle 5).
Big, rambling post out soon.
