I am in the process of drawing together the information in order to ask a question about database driver generation and installation. I am not clear whether this is best suited to SO or SU. What criteria will help me choose the appropriate site?
Read the FAQs of both websites but if I were you I wouldn't go further than that.. Deciding a website shouldn't be a really big complicated process.
If after reading the FAQs you still can't decide then pick a random one and post there, worst that can happen is your post is migrated. This is completely okay for borderline questions.
