printed as, '... how on earth do we built an inspiring, ...'
I believe it should be, '... how on earth do we build an inspiring ...'
a simple error in typesetting...........

"how on earth do we built an inspiring, engaging, and enjoyable community in our own walk of life?" should be:

"how on earth do we build an inspiring, engaging, and enjoyable community in our own walk of life?

"built" should be "build"

decide on major architectural decision.
-->
decide on major architectural decisions.

"(we will focus on building a strong environment booking in Chapter 4)"
perhaps should be: "(we will focus on building a strong environment in Chapter 4)". That is, "booking" should be removed?

"... and enjoy the fruits of the labor."
->
"... and enjoy the fruits of their labor."

That is, "... of the" -> "... of their".

Simple typo: "bridged this divide by proving gateways" should be "bridged this divide by providing gateways"

How about:
"Life has taught us that consistent exposure to high-quality content can engender a high-quality response in the onlookers."

It may be that the sentence breaks across the page boundary, but it just doesn't scan well for me.

The bottom posting example as published:
> Hey All,
> I just wanted to ask what is the answer to Foo?
>> The answer is Bar
OK, thanks for the reply, Jono!
Bob

would actually look like this after two bottom posted responses:
>> Hey All,
>> I just wanted to ask what is the answer to Foo?
> The answer is Bar
OK, thanks for the reply, Jono!
Bob

Each new response is normally pushed to the right with a new angle bracket; thus, putting two brackets in front of the original communication and only one in front of the first response after two responses.

"We the press ... and there the marketing folk ..."
would be more balanced if it was:
"We the press ... and they the marketing folk ..."

Perhaps the Launchpad URL should use the https: protocol as all previous references to Launchpad have?

"Technical communities who have successfully implementated of the dictatorial model often refers to their primary leader as a benevolent dictator." does not scan.
Try:
"Technical communities who have successfully implemented the dictatorial model often refer to their primary leader as a benevolent dictator."
Or:
"Technical communities who are successful implementors of the dictatorial model often refer to their primary leader as a benevolent dictator."
Or:
"Technical communities who have successfully implemented this model often refer to their primary leader as a benevolent dictator."
Or:

"try to disengage with them" -> "try to disengage from them"

The usage I have normally seen is "engage with people" and "disengage from people". Your phrase may be acceptable, but it clanged in my mental ear.

"As time went, on he became increasingly difficult to get a hold of."
Perhaps the comma is misplaced:
"As time went on, he became increasingly difficult to get a hold of."
And if you are passionate about not ending a sentence with a preposition:
"As time went on, he became increasingly difficult to contact."

"tuition session"
The first meaning of tuition is a sum of money paid for instruction.
Perhaps "tutorial session" would carry the meaning more obviously.

"the organization sends them around the him to every conceivable conference" -> "the organization sends them around to every conceivable conference" That is, delete "the him".
