At the end of the week last week, I asked the question to my Plurk audience, "Do you consider yourself a plurk convert? If you do, I'd love to hear why?" which then led to "What would you like to see plurk add to make it better??" I am finding Plurk, more and more attractive to hold conversations and communicate despite the way I feel about the interface.
Twitter, has issues. Major issues. The more that it is broken, features are disabled and doesn't update or respond to its audience, the more it's driving people to Plurk, not Friendfeed, but Plurk. (Sorry A-Listers, ya missed the boat on this one!)
Plurk's A-Team is learning from Twitter's very public mis-steps and issues. The team at Plurk is fast to respond, and fast to implement new ideas (that are feasible) suggested by its users. It keeps its audience up to date with what's going on. Granted, the user base is not that of Twitter, and growing pains are likely going to ensue once the exodus from those tired of seeing that dumb whale (or now the bird & dragonfly), hits Plurk.
Plurk is not Twitter, not by any stretch of the imagination. Twitter is a broadcasting mechanism and an easy way to disseminate a message to a captive audience that wants to hear what you have to say. You can hold conversations between yourself and someone else, but when you compare it to Plurk, you can see the big difference.
