Not sure if that many people will see that post but I guess an official announcement can be made in the OP when the time comes.
Speaking of which, I still really think we should get a vote started.
By the way, for Skype, it can be a bit of a hassle with lots of people in a single group, so what you should be able to do (I think) is turn off push notifications for specific chats in all of the mobile apps. Then again, I think Skype has the worst apps of all of the chat services that we've covered so far, so that is a small downside to it.
For the PC, you can change notification settings and even use highlights if you go to Conversation > Notification Settings, from the menu bar up top. The dialog should look like this.
EDIT: Forgot to mention that Skype highlights match within words, rather than whole words, so in my example, pretty much all of the highlights except for the first two end up being redundant. The same is not true for Slack, to my knowledge.
