David Lee King wrote recently pondering Ask-A-Librarian services online and if they require a reboot. With the launch of Mahalo Answers, as discussed recently on the podcast, there may be a commercial endeavor to watch. An example of a question thread at that commercial endeavor can be found here.
David Lee King took a look at taxpayer-subsidized answers services. Mahalo Answers is a commercial answers service that has venture capital rather than tax dollars behind it. Metaphorically speaking, what features from services like Mahalo Answers could be adapted and have their serial numbers filed off for use in libraries? What could librarians contribute in the other direction?
