Create a circle called Google Employees if your on G+ and you'll have a live feed of all the changes as they think of them or as they happen.



I'd recommend this for anyone interested in G+ as they ask for feedback and create hangouts. Then you can ask direct questions of what they are going to do, change and add to Google. I talked about this earlier too and regularly re-post the interesting links https://plus.google.com/102614619331...ts/ML9sH1YCUw9


EDIT:

And I'm not on about any engineers. For example Vic Gundotra who is the person in control of the whole of Google+ regularly has Hangouts where anyone can ask questions where usually even journalists have to make appointments for an interview.
