Seeing as I'm off of work today, I figured I'd set my journal up to automatically load this page up on Friday, which is today for you, but tomorrow for me. Anyways, enjoy you crazy kids!
Found this on Blogger.com's blogs of note section:
And with all that, I present my thoughts about all the 1s and 3s in the two Matrix movies. Many we've known and talked about, but bear with me.

Neo is, of course, the ONE.
Yes, NEO is an anagram of ONE.
Neo's room number in Matrix is 101.
The floor # that the 3 heroes (Morpheus, Neo and Trinity) go to to visit
the Merovingian in Reloaded is 101.
The highways mentioned in Reloaded and shown are the 101 and the 303.
The room # that Neo's trying to get too, but is shot instead by Smith at the end of Matrix is 303.
The Oracle's apartment is on the 13th floor.
The address for the building where Neo meets Morpheus for the first time in Matrix is 1313.
Trinity, of course, means THREE.
Trinity's room number in Reloaded is 303.

Neo=One
Trinity=Three

The reoccurring significance of 1 and 3 is important to the series because the Brothers are trying to establish to the viewer that the trilogy is really about the love between Neo (1) and Trinity (3). It permeates throughout this trilogy. The love story is the heart and soul to these films and the numbers are there to support that concept. That's why we see a significant event happen between the two lovers at the end of both movies, and a long, searing look of the two together embraced as ONE under the arch (a sign of divinity). I predict that another significant event might happen again between these two love birds at the end of Revolutions. (Baby, anyone?--That'd make the 2 that are 1 become 3!) The love story will probably be the deciding factor to the survival of the human species and for the co-existing of human and machine. Just as Jesus brought together Jew and Gentile in the New Testament, Neo will bring together human and machine.
