Another point to mention is that 1 titan loss is generally reported and talked about for weeks/months after the fact.
75 titans were destroyed in one engagement.

Also, Titans are mostly around as a deterrent. Both sides are aware the other has them, but I can't think of many engagements (other than a single, usually drunk, titan pilot doing a "drive by" on an unsuspecting target) that escalate to the point of people "dropping" titans on grid.
This is true. Bear in mind, my experience in EVE doesn't extend quite that far. My own character is capable of flying battleships (the largest sub-capital class of ship) and freighters (a special type of capital ship), but I've never even seen a titan in-game. (The largest class I've seen is a carrier, owned by friends in an allied corp with a POS in lowsec.)
