Am relatively new to Wordpress, but fairly long history of web site development using adhoc tools...
Am interested in this plugin, but am not quite sure it does what I want.
What I'm looking for is a way for any posts I make to G+ end up visible on my WP site. Ideally they'd appear in a widget (shortcode). My preference is that they not be turned into WP blog posts. It's not clear from your site what your plugin does, I suspect the latter.
Therefore I was going to play, but then I couldn't configure it. Issues:
* my G+ profile is my name, not a number? still OK?
* I don't have a page ID, OK to leave blank?
* Google+ activities import looks like the way to go, but the Google APIs info is way out of date, and I couldn't figure out how to set this up. Unable to get a client ID and secret.
