I looked at my website on a mobile phone last night and I was appalled at its ugliness and lack of usability.  So for now, I enabled Alex King's WordPress Mobile Edition plugin.  If you're using a mobile phone to access my site, let me know what you think.  If this doesn't work, maybe Google's mobile viewer, Skweezer, or Phonifier will. 

Update (2007-02-08 10:51am):  I disabled the plugin because most mobile phones have a choice between "optimized" and "wide page" modes.  Optimized mode should display things nicely.
