Beau Smith has released a first version of DashOff, which provides something like an even further compressed take on what Arvind's My Blogs widget does, though with some extra options: The blog listing can be sorted by name, creation or last update, and item counts can be toggled on or off.

I haven't been able to get this working in my 4.1b3 installation, but it's fine on an early svn build and also 4.01, so it's probably due to some of the interface changes that are underway.
