Most recent blog post block

Note that the block displaying "recent blog posts" cannot be easily customized to display fewer than 10 items. You have to modify the source code, the number is hard wired. There is a forum discussion on this limitation. See:
http://drupal.org/node/15635

Another Alternative

just create your own "recent blog posts" block with some snippet code:

one user blog:
http://drupal.org/node/23230

all user blogs:
http://drupal.org/node/23229

and put a more link to the /blog
:-)
