I have to disagree here.  First, I'm not a buddie, I'm a fission yeast
person.  
Second, the two hybrid system is a TOOL, a METHOD , a TECHNOLOGY.  It's
analogous to using E. coli to make plasmids.   It uses yeast as a small
Eppendorf tube.  If you will, it's a tactic, not a strategy.  This is not
to disparage its utility, but it is not an end in itself.  Yeast is
important as a biological system, not just as a kit.

So far most people have responded to my discussion topic either here or
by email, by suggesting that significant yeast work consists either of
limited technologies that the higher-cell types have exploited, or of
their own corner of experimentation.  I had hoped for a little more from
this community.

 I think the APYG ("awesome power of...") is making significant
contributions to many cell biology problems.   IMHO,  signal
transduction, secretion and localisation, and cell cycle are all areas
where yeast work is advancing our understanding of basic biological
problems.    The yeasts are biological systems in their own right, and
answering  questions in yeast really DOES make a difference to studying
them in higher cells.  I shouldnt have to persuade this audience of the
utility of model systems.   yeast is more than a system to get protein x
to interact with protein y.  The biology of our favourite organisms tells
us a lot about biology in general.  I know (and have just told you) what
I think are exciting current topics.  I wanted to generate a discussion
and see what others think.  

So, let's try again!  Tell us what YOU think is exciting right now, and
why.
