I like that you can talk one way but have many different people see it so they get all of your points in their feed as well! It's really helpful for keeping track of threads/conversations when there are several involved at once - great tool if used properly!! There isn't much about this app specifically or its functionality which makes me dislike using them.
They seem pretty reliable overall though considering how popular these types apps tend be nowadays. If nothing else maybe try out some free trials? We're trying to figure ways we could effectively use social media channels without having our community members feel bombarded by posts from us daily while still maintaining an open atmosphere where everyone feels comfortable sharing things openly within our group.
