Reminder on bumping thread etiquette/preferences?

I want to post a IMHO thread about my musings about getting the H1N1 vaccine. There is a perfectly good thread about it (WITH a poll!) whose last post was 12/19/09.

What are mod preferences on whether I should start a new thread or not? The time passed here is around that mark that my judgment finds ambiguous.

Thanks!

Go ahead and start a new thread, and link to the old one.

That poll is very out of date if it’s the thread I’m thinking of.

Back in March, I bumped a CS thread exactly one year to the minute after the OP was posted. (Mind you, the OP was mine so it had attracted zero replies in the intervening 365 days.)

Is this a record?
