You may be right. Maybe its best to only have jargon until the software is ready for prime time.

My general counter argument to jargon filled websites is the great ending of Trading Places:

   What about lunch?
   The lobster or the cracked crab?
   What do you think?

   Can't we have both?

Why can't a website have both a clear explanation for normal people, followed by all the jargon necessary for the target audience?
