UPDATE, May 13th, 2009 - Read the interview with Robert Daneri, lead designer of Heroforge 4E, exclusively here on The Core Mechanic.
I "rediscovered" HeroForge this weekend - and I'm happy to report they seem to be making nice headway towards a new HeroForge 4th Edition Dungeons & Dragons Character Generator. Currently, it is in beta testing, and it looks WAY better than the character generator available from Wizards of the Coast's D&D Insider... oh wait, they haven't released one yet... [snarky snark!]
I'm also really enjoying the 3.5 Town Generator (there's actually two of them) and a few other of the Hero Forge tools from 3rd edition. Real nice, major time saver - catalyst for the imagination if you know what I mean.
Check out character generator - its FREE CHEAP and looks very promising. Here are some screen shots:

I also want to throw in a shout out to http://singularmoments.blogspot.com/. It's a low-post rate RPG blog, but there's some good stuff over there (including this link to an old WotC City Builders Web Enhancement that I forgot about).
This post was all the result of reading Cole's excellent post on "Creating City Maps". Thanks Cole!
