The mini-blog is a neat idea. It allows us to post quick notes, including from IM and even from a cell phone. Given how events sometimes run in Israel, this is a great ability.
However, the service provider (Twitter) has been having major load issues. The ability to post by IM has been down for a month, and the mini-blog display on the sidebar stopped working.
So for now, until Twitter gets their act together or another service comes along, the mini-blog is offline.
