Just a quick proof of concept hack..
I modified twitter-cmdline script to fit mon‘s alert specs..
Download twitter-cmdline-1.03 and place it in /usr/lib/mon/alert.d (or appropriate path of your mon installation).
Then grab twitter.alert and put it there too.
Run twitter.pl and give your twitter credentials (stored in ~/.twitterrc the first time it runs). It’s probably a good idea to create an extra twitter account for this.
Now use twitter.alert in your mon config to send alerts in twitter, where people can follow them!

Don't fear the penguin 
I am really thinking of creating a twitter-like service for system administrators to be used this way.
This service was the reason I created a twitter account :-)

@stsimb:
laconi.ca and a server outside our network(s) seem like a viable start.
seemed buggy to me, testing jisko atm.
