This is an OK article, especially the accept all reasonable invitations. But in the circles I'm in "bring a friend" usually means you're welcome to bring your significant other. I used to plan plenty of gatherings, and that's what it usually turned into (couples night out). That's fine for meeting new people, but not particularly useful for making "someone fall in love with you in 90 minutes" or meeting single people in general. Anyhow, this advice is great if you want to be a social hub/coordinator, but doesn't guarantee you'll meet someone for a relationship. Weekly is a bit excessive, take a break for yourself every once in a while.
