Be more transparent about what you're doing to the service.

When Plurk works well it is a great service. For the past several months, however (since around October 2008) feature changes, system instability, and other changes to the service have seriously diminished its capability to be an engaging social network. Adding to the frustration is the fact that Plurk is pretty much a black box company—aside from a blog that's intermittently updated and not publicized and *rare* public timeline posts, there's no communication from the development team about what's going on—something I think is critical for maintaining your customer base and expanding it. I encourage—BEG—the people behind the service to first, stop changing features, adding features, and generally futzing around with the system. PLEASE focus on making Plurk reliable. New features should come only after you're able to consistently deliver existing services. Second, please provide clear, obvious, and regular communication about what's going on. Users shouldn't have to hunt around on the Internet to find a way of communicating with you. If your staff isn't willing to communicate honestly and openly with your customers on a regular and continuing basis, then you should stop altogether—inconsistent and irregular feedback from staff is possibly more annoying than the plague of problems currently affecting the service. You need a public spokesperson to keep customers apprised of what's going on (especially in times like now where your reliability is dismal) or people will give up and look for a competitor.
