Before I get into anything specific, I'd like to make some disclaimers 
and try to dispel some common misconceptions.

First of all, it should go without saying, but what I right in this, for 
lack of a better word, column is my own opinions based on my own 
experiences. Blind people are just as diverse as the sighted population 
and I do not speak for all blind people nor can I lay any claim to being 
representative of blind people as a whole. Other blind people will have 
had different experiences from my own and will likely hold different 
opinions from my own.

Second, I'm pretty sure the idea that losing one sense boosts the others 
is just a myth. If a blind person seems to have super hearing, it 
strikes me as probable that their hearing isn't actually any better than 
average, but that they've just trained themselves to extract as much 
useful information from ambient sound as possible, perhaps even 
subconsciously, and there's no reason to think a sighted person couldn't 
learn to use their other senses just as well. To use a gaming metaphor, 
many sighted people dump all of their sensory skill points into vision 
without even realizing it while the blind are forced to invest in their 
other senses.

Another common misconception is regarding Braille. Namely, the 
percentage of blind people who are effective Braille readers is much 
lower than you probably think it is. I've read estimates of the Braille 
literacy rate among blind people that range between one and ten percent 
and suspect the order of magnitude depends on how you define literacy. I 
myself know the Braille alphabet, learned all of the standard 
abbreviations and symbols representing common 2- and 3-letter 
combinations when I was in middle school, but between learning and when 
I went blind in my mid-20s, I forgot most of the abbreviations, and my 
touch reading speed is dismal, so poor I haave difficulty keeping 
letters in working memory long enough to string them into words and 
words in working memory long enough to string them into sentences... I 
can technically read Braille, so I might be in the 10%, but calling me 
literate is like calling a child who has to sound out every word 
literate.
