Thoughts on my first DLANC Election

Last Thursday, I voted in my first Downtown LA Neighborhood Council election. It was a very simple process. As I was allowed to vote for only three contests, I filled out my ballot in less than a minute. I went into the election with the assumption, that the election was by majority. Now that the unofficial results are coming in, I'm surprised to learn that election is by plurality. In the case of a tie, according to the Unofficial DLANC Weblog, the contest is decided by a coin-flip. That seems ridiculous.

Why not use Instant Run-off Voting? My first exposure to IRV was when I was a student at UC Berkeley. The Associated Students of the University of California has used IRV for its elections for its 5 officers and 20 senators for many years. If the ASUC can pull it off, why can't the DLANC?
