Sometimes posts get downvotes "in the noise"; I've had some of my posts go to -1 or even -2 before jumping to >30. It happens; people have axes to grind, think you're stupid for asking a question, etc. and by chance sometimes they cluster just after you posted. Don't assign too much value to it; it's very rare that I see a normal on-topic question like that downvoted.
