Great questions!
> Handling compaction for long lived apps/pages?
That's a very common question and something I'm planning to ship a solution for soon. The basic idea is to give each event some more semantic "meaning" by annotating the event definition which allows you to express which events "semantically overlap". For example in a todo app you could express that the "todoCompleted" event for a given task id can compact other "todoCompleted" / "todoUncompleted" events for the same task id.

> IMO events are nice, but also require discipline and good design w.r.t code
Yes, I agree with that. When it comes to data there is "no free lunch" - it's all about tradeoffs. I prefer the tradeoffs of event sourcing though for my own use cases such as Overtone.
That being said for many situations (like older client versions etc) there are pretty straightforward ways to address those concerns. Always depends on your application use case and possible tradeoffs though.
> Overtone looks sick. I've been using Spotify less and less because of janky UI and constant UI changes, would love a replacement. I see that it supports multiple sources, will it offer offline playback?
Very excited to hear! I'm sharing your frustrations which is why I'm building Overtone (next to many other reasons). Re "offline playback": That will depend on where your music is coming from. e.g. for your own music collection in Dropbox (or similar) it will be supported. For music streaming services like Spotify it will depend on their terms.
Hope that all makes sense?
