The hangouts quote icon in Chrome takes me to a page that wants to have me do a voice chat. Not interested. I click on the "text" image and it opens a column on the right that wants me to invite people or enter a "/" to get a help page, that tells me nothing.
In short, the icon in Chrome is a complete waste of time. Doesn't load my contacts for text messaging. I guess I'll have to go to facebook to use their messenger app to do my communications. I wish people would quit "improving" stuff that works fine.
