I haven't seen many off-topic questions in the sections you mentioned which belongs in 'Beginners & Help'.

'Beginners & Help' belongs to 'Other' because users make/post threads/questions which is not related to Bitcoin. So these questions will be off-topic if it is moved to 'Bitcoin' category. This fits whete it is now. No need to move IMHO.

Edit: redsn0w beat me.
