One tool which has yet to appear for global AIDS professionals is a "knowledge base": a question and answer area in which visitors post and respond to questions, and all text is captured in a searchable database. The only application I've seen that approaches this is the Q&A area of the IAEN -- an application that is currently promising but neglected (due to funding limitations). The best examples of knowledge bases -- and there are many of them -- come not from public policy but from the commercial sector. Nearly every user support area of technology or consumer information firms rely heavily on them, such as offerings by Dell (including knowledge base, online community discussions, feedback opportunities, and other community applications). Ah, if we only treated the AIDS epidemic with the same attention as our laptops.
