I posted a question there (about where to find the RSS feeds) and nobody answered. It looks like nobody else has posted there either. So apparently this widget is no longer used, and questions should be asked in some other way?
For what it's worth, I find that when I say something using the Intercom widget I usually get a response within a few hours, and quite often within minutes.
Nah, I answer stuff almost every day, though usually Ben Pace does more of the Intercom management, and he was at EA Global in London for the last few days, so he should be back on it in the next few days.
