Re: In the absence of a better medium...

Better medium?  
How can you find fault in the marvel 
that is the email? 

It allows us to express ourselves succinctly 
while, with the aid of a suitable tone, 
affording us the ability to attach emotion. 
Don't lament but rather embrace the removal of human interaction 
and the associated awkwardness: 

There is no uncomfortable eye contact, 
no colloquial insertions; no 'um' or 'like'
no fear of mispronunciation.  

You speak of better media, 
I say look no further than your keyboard 
or PDA penscreen or mobile phone. 
You will find the best medium 
right there at your fingertips.
