Then there's a new service out there called Summize. With it, you can search what's going on today in Twitter. And just like Dogear, you can subscribe to search results!
So if you are interested in seeing what the world is twittering about Lotus Connections, subscribe to these search results! I, for example, have already learned about customers who are deploying Lotus Connections v2 Beta 2. I also learned about editors who were writing stories about Lotus Connections. I, of course, now follow them within Twitter and, thus, get to expand my social network outside of the firewall!
