Forgive me, +Dustin W. Stout
, I'm no Google+ Guru but I don't believe there is any written rule on how I should distribute my posts!
I appreciate your feedback but it does come across a tad patronising. How can you ever be 100% certain that any content you do share via your "Notification Circle" is relevant to your audience? Yes, you can target a number of individuals who you perceive to be "interested" in your content but there is no definitive barometer. Like I stated previously, it is quite uncommon for me to share a Google+ post via email notification so I have no intention of invading anyone's personal email to the point that they are inundated with posts.
I'm aware that not everyone may take an interest in what I'm sharing but that can apply to any form of outbound marketing. Even if I sign-up to receive a specific newsletter from a company whose products appeal to me, there's no guarantee that they engage specifically enough we me to produce a click-through or purchase.
I congratulate you on your "100-250" click volume but, at the same time, have you ever wondered about those who don't click? Exactly. It would be impossible to engage every single user you are interacting with. Any how many people are you actually targeting? Is 100-250 clicks a high rate of conversion?
At the end of the day it all comes down to preference. Google+ has provided users with the option of sending an email to their circles. It is there to be utilised. How exactly to utilise it depends on the individual themselves and their belief in what they are sharing.
