no date in URL or main page

These changes will remove the dates from your index page and change the post url so it only has the title (no date).  The advantage is that your posts become timeless (as long as the content holds up), i.e. someone coming to your blog five years from now won't scoff at some old outdated advice that (hopefully) still holds true.  Notice that Matt Might doesn't put dates anywhere.

Problem: all your old post URLs (with their date format) will be invalid.  But those URLs are mostly back in old twitter posts which fade into oblivion anyway.

No worries if you don't merge this in.  Just consider it an example if you decide to go this route.
