I would think there is space for more noise talk.
For any new podcasts, I would probably suggest two things:
Some unique own angle how to approach "podcasts". What could be done that others ain't doing? What could be some sort of unique contribution? Doing podcast with template of first mentioning some recent listening, then track-by-track talk of classic name.. ehm.. sounds like there us that already...?
Advantage of Noisextra doing is my second suggestion: Editing things sure is time consuming and annoying work, but for listener, in case when 30% of episode is ...uumm.. so.. umm.. so.. yeah.. haha.. ummm... I think it would be good to do some quick editing.
Other than that, like said, I would assume there is space for more noisepodcasts and future will show what have lasting energy and where things will develop. Will check when new things happen...
