We use partychat extensively, and everyone who tried out the new hangouts faced the same issue: Our partychat bot won't even show up in the list. Messages sent from either side were lost. Ultimately, we have decided to ask everyone to "undo the upgrade" as of now.
While we're on the subject of typos: the title of the main workonomic page is "workonomic - manage your time, without loosing it." It's also crept into the google results for workonomic.
We are looking for alternatives.
