Would anyone be interested in a feature that generates QR Codes for questions to increase their visibility? With the proliferation of smart phones, this may actually be an effective way to bring more people to the site.
Specifically, a QR Code could be
- accessed via a link below a question alongside link|edit|retag|flag.
- accessed via a link below an unanswered question along with the text Know someone who can answer? Share a link to this question via email, twitter, facebook, or linkedin.
- displayed in the right column next to the question.
My original idea was to have these QR Codes visible on public transportation, where many high-tech workers have free time to kill on their smart phones. Why not try to answer the question of the week on your way to work? The problem with this, of course, is that advertising space on public transportation is not free; nevertheless, I thought that the idea was worthy of discussion.
QR Codes could also be placed on public billboards, such as those on college campuses. What better way to introduce the programmers of the future to Stack Overflow?
All this being said, I'm not really arguing that Stack Overflow is in dire need of more traffic; I just think that there are merits in the use of QR Codes to promote Stack Overflow and am curious about how much interest there is in the idea.
