The latest episode is perfect for any HP fan - we get to see what the various podcasts in the HP fandom are about as well as the people behind the curtains.
IMO, as a slash shipper- actually, even as a HP fan - you owe it to yourself to try it out. Personally, I find podcasts to be a very different way to enjoy fandom - and in this case, the slash too. And they're just awesomesauce.
Oh and if you do listen to the podcast and have some opinions, send 'em a voicemail via skype. Doesn't have to be a speech - just your thoughts, even if its less than 30 seconds. It might just be featured in the next slashcast episode XD
But seriously, y'all should just call in to spread the love.
