It’s about time! Hangouts for serious use is awful on a Mac, and Common Hangouts has been fantastic to use so far. I’d previously switched all work IM over to iMessageMessages on Mac, but that doesn’t support group chat. Common Hangouts has essentially the same layout that I like, except with full Google Hangouts features. Awesome stuff!
Also, MakeUseOf is a great tech blog, and I recommend it.
