Most style guides have changed their position on beginning a sentence with a conjunction.

In most cases where somebody actually would end a sentence with a preposition, there doesn't seem to be any rational reason not to do so.

In most cases where somebody begins a sentence with a conjunction, they are trying to join the thought of that sentence to the previous sentence. Usually that is properly done within a single sentence. Sometimes one can make an impact on emphasis or style by breaking the conjoined thoughts into two sentences. I think this would qualify as using the sentence break as a super-comma, as I mentioned above. Doing that all of the time, or doing so when a strong break is not necessarily intended, tends to dilute the impact of the non-standard usage.

So I would agree that one has the freedom to start sentences with conjunctions, but one should use that freedom wisely. For example, I would agree with doublespiral that the first six sentences by Kevin Gemmel after "A closer look:" are notably disjointed and distract from following his thoughts.
