Community meetups are a great way to meet new people with similar passions and interests as your own. It's also a great place for the community to exchange ideas. Often you get an interesting presentation to boot.
I've also been talking with the SV-GTUG (Silicon Valley - Google Technology User Group) organizers about doing a GWT presentation at an upcoming meeting. We don't have a firm date yet, but I'd like to start collecting your questions and suggestions for material you'd like to see covered. You can vote on other people's ideas or post your own questions here.
Finally, if you know about or organize a local user group that has developers interested in GWT, let me know. I'd like to hear about your group, and perhaps there's a way we can help make your meetings even more compelling.
