Something you seem to be missing though is that in general it's nice to not 
just endulge in an endless series of hacks in your specific area of the 
system.  IWBN to at some point devote some time to help fix more general 
problems that will benefit the system as a whole rather than adding hacks 
that just benefit yourself and require someone else to clean up when they 
eventually add the more-architected solution.  We are all very busy, but if 
everyone just did hacks and never put any effort into improving the general 
infrastructure, we'd have a royal mess.
