It's a shame the journal browsing feature is gone. That and the forums, also gone, are the only ways I knew of easily finding new members.
That said, I find it hard to believe that anyone is joining blip now, it has so little to recommend it for newcomers. I know I'm commenting far less, and I haven't subscribed to anyone new for ages. It's such a shame that all the massive goodwill of blippers has been squandered for the lack of some simple, basic communication. Over three months now.
