#Kasts for Linux has had some updates since the last time I looked at it. They are now a viable alternative for me over #gPodder which has been unstable and unusable for the past year. gPodder used to very reliable, but things got so bad that I was seriously looking at #Clementine as an alternative. Very happy to see that Kasts has stepped up their game.
Good news everyone! The gPodder media RSS reader / podcast client / podcatcher had a bugfix release (3.11.3) last week (subscriptions to youtube user ID URLs now work, yay!).
