It was only yesterday that Google posted the latest Google+ platform office hours on YouTube. That one was from last weekend and contained lots of juicy info including a live coding session. It might surprise you then that Google was a little late in getting one of their past hangouts out on YouTube. It might be old, but it's still a good one.
While the above issues take up the majority of the hangout at a whopping 24 minutes, the team still some time out to answer some important viewer questions. The one that may be the most pertinent to Google+ users is if Google has plans on bringing the old +1 button back. I personally like the new sleek look of the +1 button, but I'm sure the old one had its fans as well. Well, Google says that the majority of users seem to like the change to the new +1 button. They do welcome any and all feedback though on the matter.
Speaking of feedback, Google has a handy Google+ platform issue tracker where developers can submit issues they have with the platform. These kind of things usually don't see a reply so it's no surprise that some developers may feel that Google isn't paying attention. That's not the case according to the Google+ team. They say that they read each and every one of them and discuss them internally.
Check out this latest Google+ hangout and become informed. The platform is constantly changing and it's good to stay on top of said changes.
