The interface is kinda clunky.
When you're looking at the "Your Blog" page (where you see the intro to each of the 2 entries you have in your particular blog) at the lower-right corner of each entry it says Views and Comments, and there are 4 little icons that are clickable. The 2nd icon looks like a pencil, and if you hover over it should say "Edit Blog Entry" and if you click on that you can edit the contents of that entry.
While you're in that edit interface, one of the options is "Delete" if you still want to delete the entry.
