> have to pay attention to 4 different technical discussions

Seems like a mistake to have actual technical discussions in a stand-up. So yesterday I've worked on X feature, I've gotten pretty far but I'm being blocked because of a dependency on Y feature. I'd like to continue today, developer Z (who is working on Y feature) can we discuss this after the stand-up? Of course, I could've communicated this before - and maybe I've already done that, but the rest of the team doesn't know. What if they want to pick up a new story that has a dependency as well. Should all this communication just happen in emails or slack messages? That's fine I guess but it doesn't hurt to have 15 minutes to get a good view of what the rest of the team is doing.

Once you get into the nitty gritty you should honestly just say hey let's take a subset of this group and discuss it after. Works for us. Non-dev people shouldn't be there, or at least shouldn't get turns unless they're actually working on issues in the sprint.
