Plurk all the way. I must say that Plurk is an all around means of communication. I have used Twitter in the past with little success of gaining true friendship. Usually with Twitter people update based on what the are doing and most do not respond to a single thing you say. I joined Plurk and within 3 days had 60 friends who would hold conversations with me and intellectual ones at that. I have gotten so many great ideas from my pleeps it is not even funny. If you are just looking for a way to present your website or promote your product then I suggest Twitter , but if you are looking for anything more, such as conversations and communication the I suggest you give Plurk a shot. As an added bonus the service is up more than Twitter.
