Tech-related volunteer gigs

jeffomatic writes: Here's a question for Service Day: what kind of volunteer opportunities are available out there for the technologically-inclined? I'm a software developer and I'm wondering if there's anyone in the field engaged in pro-bono work, like IT or teaching or web design or whatnot. I'm not at all above rolling my sleeves up and working at shelters or the local park, but it occurs to me that my professional skills might be usefully applied in the service context as well. I'd like to hear about what other people are doing, in terms of projects, time commitments, organizations, etc.
