If You Like This Blog Entry...
Here's a little Christmas present before the end of the year... You might have noticed a new little feature pop up on our event pages yesterday, tucked under the list of attendees -- suggested events based on the interests of everyone going.
For us, this has been a quirky way of discovering new events. How 'bout some examples?

People seeing
My Morning Jacket in San Diego are also interested in the upcoming
Cold War Kids,
Of Montreal,
Deerhoof, and
Snow Patrol shows. If you're going to the
SXSW Music conference next March in Austin, Upcoming suggests
SXSW Interactive,
SXSW Film, and several related parties that week.
BookExpo attendees in NYC are also interested in seeing
David Lynch speak at Barnes & Noble. Fun!
The more people going, the better the recommendations... So if they seem a little funny at first, check back later as more people find the event. Serendipity tastes good.
Are you basing the suggestions just on users linked to the events - or are you also factoring in tags and groups in common?
Is greater weight given to events being attended by the same users than events just being watched?
Thanks!
(Oh, I did notice that this potluck of yours was suggesting the other two in the monthly series.)
