We had a great turnout at the latest PostgreSQL users group meetup -- around 35 people showed. (Oh and not the group of stylish "Hi5 folk" you see to the right :)
Ram and I went over the PostgreSQL based DB architecture we use at Hi5 after the obligatory pizza feed. Quite an interesting crowd, some newbies, and some old hands.
My best line of the night was in response to a question asking us when we were going to use a specific feature -- my answer was that there were more people in the room than there were employees at Hi5. :)
The complete presentation is online for the curious.
