I agree entirely (and have said so on several occasions). Answerbank has more than 80 topics which, in my opinion, is too many.
Here are a couple of examples: If you click on "Food & Drink" you can post a question directly into the main heading but there are also four sub-headings including one for "Drinks" and one for "Food"!
Also, if you click on "History", it opens up a topic headed (in the red bar at the top) "History & Myths". There is also a sub-heading called "Myths & Legends".
This is unnecessary duplication.
It would be better if a topic has sub-sections for it to be impossible to post questions directly into the topic heading. This would encourage posters to put their questions into the most appropriate section and could result in their question being answered more quickly.
