In Twitter say: follow observatory
Once the observatory has greeted you (can take two minutes) tell him what to look for:
@observatory track openid
To silence the bot say eg 'off openid' or 'off observatory'. Right now you can only track one phrase at a time (until things get more stable).
Right now the Observatory is tracking 10158 data feeds. The Observatory is using the data accumulated by wigitize.com. This Twitter service is a proof of concept application by ToPoints Web Technologies. The source-code and howto can be found here.
