Hi,

   I am new to the community and I understand that ASICs are pretty much required to get profitable when mining.  I don't understand why this is the case though,
concurrent use of good processors seems like it should work well to compute hashes from my perspective, after all they have run almost all clients and servers on the
entire internet until now. 
   What is the technical reason for requiring ASIC hardware?
   Why did CPU mining get removed from bitminter.com?
      I realize that it may not be optimal, but on my fairly fast machines I spend much of my time reading web pages and typing in a text editor,
      so the CPU is hardly even used 90% of the time, even though it's on.  I buy fast CPUs for that other 10% of the time when I need the juice
      to reduce my wait time.
      It seems to me that background use of a CPU would be a great way to mine.
      Perhaps the client just needs a processor usage knob next to the start button?
