ShareNotice plugin -- basic buttons per-notice to share the text & a link to the notice on other sites.
Default settings list Twitter, Facebook, and Identi.ca as targets.

Using icons built-in, and no magic offsite JS or anything so it won't slow down or break if third-party site goes down.
Default styles are a little limited, but can be customized in theme should one be so inclined.
