Weird wasn't in a negative sense, just as a qualitative descriptor of difference from what happens to the kind of English I hear every day. I am from Germany and I would probably find it difficult to listen to myself in an English language podcast due to my accent.
What sounds familiar and what strange or plain wrong is probably highly personal. For example, I've heard enough Australians speak to have a feel for that particular variant of English. When I hear it, I notice the different "melody" of it, but there usually isn't a sound that surprises me or comes unexpected. It's like when I go into the Biotech building on our university campus: They have a weird floor layout and the main staircase isn't anywhere near the main door, but I find my way around because I got used to it.
However, when I had just moved to London as a freshman and first heard my Australian professor speak, every other word seemed out of place. That was just like my first trip to the Biotech building where the simple process of walking through the corridors was constantly interrupted by doors covered 100% in hazard signs and trying to remember the turns I took. Sure I could understand the Australian professor just like I could find my way around the Biotech building back then. But it took more energy than listening to a well produced radio program or walking around the building I work in every day.
In a podcast, ideally you'd want a speaker whose voice sounds natural and familiar so that their words convert into thoughts effortlessly, yet there are so many different ways to speak. This is a problem you have to deal with as a podcast producer that writers rarely have (except when writing about aluminum/aluminium).
