What a bunch of children.
We need a grownup to run the country.
Keep America Great!
You could look at all the notables like previously suggested, but no telling if a Baker actually made your topic notable. There are shill bakers at times and some anon bakers (despite their best efforts) don't put everything trending (especially something on the bleeding edge) in their lists.
You could just post the topic that's on your mind but you run the risk of some asshat telling you that was covered some breads back.
There's no way to be certain - so (you) take (you)r chances.
