Josh and I met through Twitter. He moved to San Antonio last summer and used Twitter to find/reach out to local web folk.
We both do client services based web design and development so we wanted to have a group to meet other people like us and build community. The focus of our group is to share knowledge, connect, and offer a place to get away from the screen and chat with people in person.
Since most of us work from home or small office we also organize mid-month social meetups to get together in a more relaxed atmosphere. Our first drink/social meetup was at Lion & Rose pub.
Future goals are to continue growing and connecting SA Web Pros, bring knowledgable speakers in from far and wide, and possibly organize a conference.
