Skype is fundamentally broken. I use it on iPhone and my laptop (Mac) and neither are remotely trying to adapt to my use case, which seems to be the vast majority: I use it to talk to a handful of people (two, maybe three) I need to have a button to call each, and access the history of the conversation. Instead, I have unending lists of lists of contacts, annoying recruiters, people who failed an interview 5 years ago, spammers, and I cannot de-list any of them. And violently loud, impossible to remove, alerts for each of those thousands of people’s birthdays, for no apparent reason.
Best of the best: they somehow cannot filter Larsen loops (the annoying high-pitch wobble that comes & goes becomes louder: it’s an acoustic loop between mike & head-phones), so I have to mute every 5 seconds for a second to take those out…
