IMO, jury duty is one of the most important things you can do as a citizen. It's probably more important than voting. A competent jury is often the only thing standing between an innocent person and prison.

I've never had be judged by a jury, but if I did, I hope the jury would be composed of intelligent, thoughtful and serious people.

I've done jury duty once. It was inconvenient but I would gladly do it again.
