If you couldn't infer, I am a near-paradigmatic INTP.
>>remember that there are only 16 types so it's highly likely you'll meet like types - certainly more often than you'll meet somebody with the same birthday, for example.>>
It's a tad more complicated than this. The frequencies of the different types in the general population are not equal. For the rarer types (eg, INTP, INTJ, INFJ), you're looking at ~1 percent of the population. Furthermore, some types tend to cluster in particular social settings, eg INTPs sitting at home on the computer, or working as computer programmers and "scientists".

>>Many of these same skeptics fully endorse the Big Five / OCEAN test as far more scientific, although the only difference I see is accounting for one other factor: neuroticism.>>
Even though the Big Five holds greater empirical and statistical validation than the MBTI, I find the Big Five's descriptions "thinner" than the MBTI's. The scores that one receives along the Big Five's dimensions do not suggest any characteristics or behaviors not contained "directly" within those dimensions. The MBTI, on the other hand, points to an array of preferences for types of thinking, depending on your particular type.
