My Twitter feed is private, and I only follow people I know. Most of them follow me too, so it's a good way of communicating with those friends. I only log on Messenger on one of my computers, but my active friends list is getting smaller and smaller. Most who used to be online a lot, now mostly are offline, so I think we're not alone.
Having Messenger and Twitter in one app would be nice, if mobile Messenger apps would allow messaging people who are currently offline. Looking at battery life, I don't like to use an active connection just for Messenger.
enjoy being here while getting there
