Basecamp, previously 37 Signals, no longer offers the full Campfire service, Highrise is only available for continuing accounts, their company culture monitoring service is gone (partially implemented in Basecamp), Writeboard is gone, and their sketching app for iOS is gone, and those are just the ones I remember. They've done ok at maintaining their products, but they haven't got a flawless track record. Customers had to move off Campfire when they closed it down.
