Thanks for your input Dave!
As far as your comments, you're taking the points out of context. For example:
1) In fact, if your business has 100 followers with active engagement, your Google search engine results position can improve by 14 spots.
Ummm no. For a start i could be 8,0000 in a SERP in which case a couple of follow links/+1's or any engagement could make me rise a lot more than 14. Orrrr i could be 15th in the SERP's with wikipedia, mashable and Nike ahead of me in the SERPS you simply can't say that doing x will make you rise by y, it will vary too much.
I’m not pinpointing solely Google+ as THE SEO source. Of course if you were on page 450 on a Google search, with engagement on Google+, you would rank much higher then 14 spots. You are taking my points too much as an equation.
2) companies that incorporate hashtags into Google+ posts that match user keyword search results can experience a significant upswing in link clicks and website traffic.
Where have you got this information from? Do you mean in the main google search engine hash tags are starting to become more popular or from within G+ itself? I'd love to see some stats on this as i can't find any. By the way, the post you did advertising this(well not this, the same article on your actual site, which will cause duplicate issues, possibly) just has the automatic hashtag of google, this is surely not best practice!
In regards to this, you didn’t read the sentence before it. I’m talking about Google search engine results. Here is the news story: http://techcrunch.com/2013/09/25/google-starts-supporting-google-hashtags-in-search-queries/
3) Google+ posts have no character limitIt does!(unless something has changed since March 2013) It's a massive 100,00 characters so you get a lot, but, you couldn't transcribe an entire dissertation or thesis on there!
Again, you’re taking my points a little too literal. No professional marketer in their right mind would post a dissertation on there.
4) Google+ has branded itself as THE social network community for making connections and collaborations within the professional community
As a final aside i can't find the author of this piece on Google +(although her company is) so rather wonder how much time the author spends on the platform.
Just because a social platform exists, doesn’t mean I have to have a profile on there. But I actually do participate on G+; thanks for trying to point that out.
